There are now 3 new Alphas
Raika Seno (SR)
Kimi Kashima (R)
Setsuko Ooyuki (N)

Do these cards need to be in my Pero? Also what about the 2 cards you can trade medals for? Are those also "slayers"?

Anywho I am currently sitting at 1,146,249 Event SED if any one wants to invite me. I am having a bit of trouble taking on SEG by myself and my weak friends.

they dont need to be in your 5 card selection for your front page, simply owning the cards will give you the bonus (more if they're all lvl 100)
every PPS event comes with 1 set of Betas from previous event, 1 set of alpha for 1st phase, and 2nd set of alpha for 2nd phase. all will have effects for the current. 2nd set of alpha usually will be beta for the next event.

the cards that you trade medals for are not slayers.
