Just see card list as EvilAngel mentioned above, you will notice that event Gacha has a N card not present in N or R Gacha. Old event cards are also available, but they doesn't affect multiplier (i like redhead from old guard event but i will pick her later, is too similar like a local slut in my land)
I'm talking about the rest of cards (like Satona Okada, slayer card from first guard event), which are no longer useful for this purpose.
Slayers cards have cycles, and they only last for two events. And the second event they are weaker. After that, they lose the bonus and newer cards take the place.
in the event help, it say the n-slayer only, is in n-gacha p_p
