All the current slayer cards are listed in the game itself, when you click on the event thingy inside elite guard.

Thanks for the clarification! Much appreciated.

For those curious about the event gacha, I just tried a couple of hours ago and didn't went as I expected. Used the card reveal just to see that I had to choose between R girls already available at the normal gacha. I wasn't expecting to get an SR at first try, but at least an event R.
And there went my free nutaku gold, lol. GG WP.

[MENTION=68]Tenhou[/MENTION], if you still wanna try the event gacha, make sure you buy at least 5 or 6 tickets, the % of getting a special card increases each time you try it. At 5th attempt you should get the 100% chance of SR and put the card reveal to good use.
