********************

So new event come next week - Most big updates come Monday so I am hope it start Monday morning
They show a picture of 5 girls so I think we will get 5 new girls(1X N, 2X R, 2X SR) to catch.

Five new girls, that's pretty good. ♥

I'm really looking forward to this event. Though I'm still unsure about which cards I should level up. lol. Especially since I only have enough SR wild cards to level a total of 5 girls. There is no way I'll have enough to make 2 full decks of SR cards.

I went ahead and leveled my top girls, giving me one sexy, two babes and two moe. Sure, it will not have any typing, but i should be decently strong against everything but babe decks. If it comes down to it i'll try to level one more of another instead, but those were the cards i had at highest level already.

That said, i guess people might not be as keen on attacking a deck without any attribute? Since it could work both for and against them.

In order, from left to right:

1. • Name: Asagi Muta
   • Lvl1 SED: 1,150
   • Lvl100 SED: 11,790
   
   
2. • Name: Satoe Kukimoto
   • Lvl1 SED: 660
   • Lvl100 SED: 6,600
   
   
3. • Name: Yukari Mitsushiro
   • Lvl1 SED: 1,190
   • Lvl100 SED: 11,790
   
   
4. • Name: Ruriko Nishino
   • Lvl1 SED: 240
   • Lvl100 SED: 2,530
   
   
5. • Name: Shiki Urawa
   • Lvl1 SED: 1,220
   • Lvl100 SED: 11,820

This means that:

• None of the SR cards reach the top 3 Babe SED, but all of them enter the top 5 Babe SED (Kaori in 4th place, Yurika and Asagi tied in 5th), displacing two more non-event cards from that list.
  Now, top 3 is non-event, non-event, e-gacha; while top 5 adds three e-reward.
• The R card doesn't even make it into top 5 Babe SED list.
  Top 3 remains as non-event x3; while top 5 continues with e-gacha and non-event.
• The N card makes it into 4th place.
  Top 3 remains as non-event x3; while top 5 is now e-reward, non-event.

As you can see, low-tier players can still play without the need of investing any money; while middle-tier players can make a very good attempt with minimal cons for not spending money.
However, if you're going to try for one of the top tiers (specially in the first few hundreds), not having spend money in e-gacha in the last event will hurt you a lot.

Of course, luck/RNG, and tactical thoughts will still be a great help here, and might let you net a good position; but money spenders will be at an advantage.
