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).
