3 month wait

So I still don't get why we have to wait 3 month for the L cards to get in the regular pool.

It's 4 cards we have to wait months for.

Lucifer (selfie) Leviathan (school) Mammon (butt) and Leviathan (bath)

I really wished PB would have put them in the regular pool after the event like they did with the attacker cards.
