Some of the 4th Anni cards were announced! I'll just put them here just in case if you haven't seen them yet :) Edit: Now with the trained versions for some of them!

Two Dream Fest cards were announced for Moca and Sayo.

Moca

Sayo

And the, there's the wonderful Backstage Pass 4 cards! These are the ones that will appear in the gacha:

Saaya

Maya

Kanon

Tsukushi

The 4*'s will probably either be Saaya and Maya or Kanon and Tsukushi.

Also, the event cards!

Tomoe

Ako

Masuki/Masking

And finally, there will be a special gacha with Mashiro and Rei/Layer as the rate-up cards!

Mashiro

I seriously can't wait!!!! (I hope that the Dream Fest is nice because I'll probably only have enough for 3 ten pulls at the very least XD)
