Alright, I've tried studying the wiki as best as I could on this, and a lot of it never made complete sense to me. Take what I say here with a grain of salt, because it may not be accurate. Add to that the fact that it seems Nutaku versions of events get the backhand, like with the guard's HP, it may be pointless to follow the JP wiki anyway.

PeroPero Colosseum


PvP decks are made up of 5 cards.
The match victor is decided after 5 battles. Each card fights one other card. The victor is the one who wins 3 battles.
Since the total SED is not related, it will be easy even for new players to get involved in this event type.



Choice of opponent

->Open Spoiler<-

Focus is used to open to selection screen and up to 6 opponents appear.
You can narrow down your opponents.
If you have made a narrowing, please press update.
It does not reflect that it is not pressed.

• Only attribute ... chosen attribute of the other party is displayed.
• Only rank ... chose the rank of the other party is displayed. (Strength 1 roller → 5 roller Weak)

Picture of the character that is displayed next to the name of the opponent is the center card.
Actually fight picture that is displayed because it is five Perokorodekki is not involved in the battle.

it becomes battle screen If you choose to fight. Friend's, HELP card will be displayed in the upper left.
Opponent's HELP card does not appear until you start the battle.
HELP of his unit, in the CENTER of Perokoro dedicated unit of Perot friend, will be selected at random from among the Perotomo.
It will also re-select again HELP by reselect the opponent.
Winning percentage goes up by re-select until the HELP that is advantageous to their own attributes.


※ If you do battle at a later time is after you have made the narrow, there are times when other party has changed the attribute to change the deck in the meantime.
Moreover, it is also the case that has taken time to HELP wish.
UPDATE FREQUENTLY!

HELP Card

->Open Spoiler<-

CENTER card will be called as HELP.
Consider placing your highest SED card in the center to assist friends.
This is not a card to be placed in the center of My Pero. Please note the battle deck is separate from the home deck.
There is no reward given for helping to win a victory.

If you have never participated in this event type, you will be sent straight to the deck creation screen to select 5 different cards for battles.

Attributes

->Open Spoiler<-

If you put 3 or more of the same attribute, you are marked with this attribute.
For example: "Sexy","Sexy","Sexy","Moe", "Babe". When you finalize the unit, your attribute will be "Sexy"

On the contrary, when it is two or less the same attribute in the unit, attribute is (none).
For example, "Moe","Moe","beauty","beauty","Sexy"will be when you organize the unit in ", the attribute is "none".

The displayed attribute affects the decision of who players are willing to attack. If your attribute is not specified, they can't have any way of knowing which cards they should be using for best results.
(Non-attribute always become a deck of 2-2-1, battle choice outcome will be based mostly on luck)
---------------------------------------------------------------------------------------
Moe strong vs Sexy, weak vs Babe.
Babe strong vs Moe, weak vs Sexy.
Sexy strong vs Babe, weak vs Moe.

In the case of favorable attributes against the opponent's card, SED will be 3x
Rarity of the card does not matter for this effect.

Example) attacking the other side[/COLOR]
　　Hypnotic force 5000 Babe　　hypnotic force 9000 Moe　 Attacker wins. Babe gets a 3x bonus, so this means a 15000 vs a 9000.
　　Hypnotic force 5000 Babe　　hypnotic force 6000 Babe　 Opponent wins. SED values are not multiplied and the opposing card is stronger.
　　Hypnotic force 5000 Babe　　hypnotic force 2000 Sexy　 Opponent wins. Because of the 3x bonus, it is 5000 vs 6000.
　　Hypnotic force 5000 Babe　　hypnotic force 5000 Babe　 If values are the same, victory is given to the attacker.

Battle Order

->Open Spoiler<-

	Deck Arrangement	Battle Screen
LB (Left Back)	No. 1 left	Top
RB (Right Back)	No. 1 right	Bottom
L (Left)	Second from the left	Second from the top
R (Right)	Second from the right	Second from the bottom
C (Center)	Middle	Middle

We will fight in the order of LB → RB → L → R → C

Defensive war

->Open Spoiler<-

Throughout the event, other players will be attacking you.
In the case of a victory, defensive war is increased by one, three Perot roller ticket will have been given to the gift box.
There is nothing if you fail to defend. Attack winning streak also remains unaffected.
Many times that you are fighting, opponent does not have a way of knowing the contents of the battle, such as what was the deck.

Trap (Counter) Deck

->Open Spoiler<-

Decks in PeroColliseum are usually decks of Moe 5 and Moe 4/Sexy 1, given the percentile winning probability.
I will say that the most victorious defense deck is a daring Moe 3/Sexy 2 and the trap deck.
But this happens to be a very unsuitable deck for attack, becoming very troublesome because it's necessary to change decks every time between attack and defense times.
That's why most of the trap decks just wait until they are attacked, and then arbitrarily decide to counterattack.
Try to set your attack decks with the understanding that there will be such decks in play.

(Thanks to @YoshiEnVerde; for the translation on that)

Win Reward & Criteria

->Open Spoiler<-

We will win Perot roller ticket depending on the rank of opponents.
When you defend the attack from the other players, you can win three Perot roller ticket.
Perot roller ticket, will be lost along with the event period end.

Rank is determined by the total SED of the opposing team.
The strength will be in the order of 1 roller (strength) → 5 roller (weak).

Opponent rank	Total SED opponent	Number of tickets
1 roller	150,000 to	5
2 roller	60,000 to 149,999	4
3 roller	30,000 to 59,999	3
4 roller	10,000 to 29,999	2
5 roller	0 to 9,999	1

※ by the update, you may set the width of the rank changes.

Ticket Rewards (Needs our own input!)


If I'm not mistaken, this is the table of potential rewards for tickets earned during the PvP event period. Any numbers entered here should reflect the rewards given per roll. Numbers between () indicate how many total rolls are recorded, while the other numbers represent how many times that reward has been obtained from the box of that column.

	Pink BOX (20)	Silver BOX (50)	Gold BOX (150)	Platinum BOX (294)
Limited card (SR)	-	-	1	2
SR Wild Card 5	-	-	3	10
SR Wild Card 3	-	-	5	12
SR Wild Card 1	-	-	8	15
Gold frame total	(0)	(0)	(17)	(39)
Limited card (R)	-	1	-	1
R Gacha ticket	-	2	2	6
Peronamin	-	3	7	16
Pero Pudding	-	3	7	16
R Wild Card	-	5	12	30
3000 Pero	-	5	15	35
Silver frame total	(0)	(19)	(43)	(104)
Limited card (N)	1	-	-	1
Peronamin Half	3	5	12	24
Pero Pudding Half	3	5	12	24
N Wild Card	4	7	22	34
N Gacha ticket	4	7	22	34
1000 Pero	5	7	22	34
Peach frame total	(20)	(31)	(90)	(151)

And of course, everything in this post is subject to change. But it should at least serve as a basic guide to help with understanding.

On the help part, it exactly says as you're guessing: Helping somebody win will net you no rewards, and the battle deck is a different deck from your profile 5-card list. The note there is warning you that the card selected for help will be the main one in your deck, not in your profile.

The trap advice is the following:

Decks in PeroColliseum are usually decks of Moe 5 and Moe 4/Sexy 1, given the percentile winning probability.
I will say that the most victorious defence deck is a daring Moe 3/Sexy 2 and the trap deck.
But this happens to be a very unsuitable deck for attack, becoming very troublesome because it's necessary to change decks every time between attack and defense times.
That's why most of the trap decks just wait until they are attacked, and then arbitrarily decide to counterattack.
Try to set your attack decks with the understanding that there will be such decks in play.

Thanks, updated it to reflect that.

I'm probably not the best one to be writing these considering I can't even read it without google backing me up.

Now, for a quick explanation on the winning prob of those two decks, it's basically based on the low time cost needed to build one.

If you didn't find out yet, SED curves for cards follow a simple set of rules:
SED gain per level for Moe cards decreases as you approach top level.
SED gain per level for Babe cards remains relatively the same for every level (it might fluctuate, raise or drop a bit)
SED gain per level for Sexy cards increases as you approach top level.

What this translates to is that Moe cards can reach 60% of their top SED around Lvl40, while Sexy cards don't reach that amount before Lvl80, and Babe cards achieve that around Lvl60. Of course, almost all Sexy cards have at least 10% more top SED than any Moe of the same rarity.

Crossing that with the fact that matchup bonus means a card of any attribute can defeat a card of the weaker attribute being just one third as powerful, this means that:
Matching SR vs SR, a Lvl20 SR Moe will most probably win against a Lvl100 SR Sexy. Similarly, a Lvl45 SR Sexy will always defeat a Lvl100 SR Babe; and a Lvl30 SR Babe will always defeat a Lvl100 SR Moe.
Even more! Matching your R vs an SR, you only need a Lvl40 R Moe to defeat any Lvl100 SR Sexy. Once again, values for Sexy and Babe are higher (around Lvl70 and Lvl50, respectively).

What this means is that players that aren't in the top percentile, or don't want to throw too much (or any) money into the game, can easily make a colliseum-winning deck just by rasing 5 R Moes to Lvl40~50, and/or a couple SR Moes to Lvl20~30; and then targetting Sexy predominant decks. That's actually buildable in a few weeks (It took me about two weeks to top level 2 SR cards, just from daily rewards, gacha/chances, and other miscelaneous rewards...).

No problem. My ability with the JP language is not that far from yours. I just have enough experience to keep my trusty EN-JP dictionary at hand, and then double-check anything that seems too spotty from the google translation and try to fix it.
I could do a full translation, but it would take too much time and effort, so that first Google pass through the text saves a lot of worktime

I'll add here what I posted near the end of the thread for Event 1, regarding the Colliseum:

Currently best cards are:

->Open Spoiler<-

• Super Rare
  
  • Event-Only:
    
    • Chikusa Uno (12,700)
    • Miyu Kisaki (11,830)
  • F2P:
    
    • Hiyori Katagiri (11,000)
• Rare
  
  • F2P:
    
    • Marie Mochizuki (7,270)
    • Airu Shirayuki (7,080)
    • Noriko Takase (6,410)
• Normal
  
  • F2P:
    
    • Riza Shimozono (2,860)
    • Ouka Komai (2,700)
    • Shuri Kanno (2,370)

The values posted in the wiki state the matchup bonus is 3x...
That actually means a lvl maxed card can easily defeat any matchup lvl maxed card one rarity tier up, and any lvl maxed normal can defeat any matchup lvl50~60 SR card.

That's a huge advantage given to matchups.

Currently, minimum requirements for having any chance are:

->Open Spoiler<-

• Against all Super Rare deck
  
  • Lvl100:
    
    • 3,944: No N card. Any midleveled R. Any lowleveled SR card
    • 3,667: No N card. Any midleveled R or SR card
    • 4,234: No N card. Any midleveled R or SR card
  • Lvl75:
    
    • 2,958: No N card. Any midleveled R or SR card
    • 2,750: Lvl90 Riza Shimozono. Any midleveled R or SR card
    • 3,175: No N card. Any midleveled R or SR card
  • Lvl50:
    
    • 1,972: Any high leveled N card. Any midleveled R card. Any low leveled SR card
    • 1,834: Any high leveled N card. Any midleveled R card. Any low leveled SR card
    • 2,117: Any high leveled N card. Any midleveled R card. Any low leveled SR card
• Against all Rare deck
  
  • Any N matchup card will work for evenly matched lvls.
  • Any R/SR matchup card will work, regardless of lvl.
• Against all Normal deck
  
  • Any matchup card will work, regardless of lvl.

My SED tables are quite full of holes, so I can't calculate exact thresholds for R mid+ levels, or most SRs.

OK, from the people that played the JP card, HELP works the following way:

->Open Spoiler<-

Every time you attack another player, a random PeroFriend is selected, and their center card given to you as a Helper Card.
The first of your cards that is knocked out gets replaced by the Helper Card (same for your opponent).

An interesting tip somebody gave is that you can cancel an attack (The process is something like Enter List of Opponent -> Choose Oponent -> Start Battle) and reselect the opponent to get assigned a new helper card, until they're both useful to you.

Here players can check girl power of all girls in English version at level 100.

List of Super Rare Cards - PeroPero Seduction Wikia

So much great info. Thanks for all the hard work Kotono. ♥

Ugh, an RPS style of PvP?...I may be somewhat obsessed with trying to get every card there is in the game but I don't do RPS style anything...I don't even...just...yeah...

Not that it has any particular bearing on the ability to understand, but in your "Win Reward and Criteria" section, "Total Hypnotic Force of Opponent" probably means "Opponent SED". Can't provide much of a basis for it but if you remember that magic circle-like thing that pops up from time to time in the game when you do stuff like level up cards, use wild cards, or when the game loads, it's a triangular magic circle where the points are labeled "Seduction Skill" and the connecting circular bars read "Peropero Saimin", Saimin meaning hypnosis.

Just something to consider.

Yes, hypnotic force is referring to SED. I usually change it when I see it, but that is how it comes out when google is translating the wiki page for me.

Hey, at least the translator somewhat gets it right. In the aigis wiki it translates attack range as cum degree

The term in JP is literally Saimin Power, which translates to Hypnotic Power. We're the ones using a different term (Seduction Power)
