Slime Against Humanity - 2G
Sorcery (Common)
Create a 0/0 green Ooze creature token with trample. Put X +1/+1 counters on it, where X is two plus the total number of cards you own in exile and in your graveyard that are Oozes or are named Slime Against Humanity.
A deck can have any number of cards named Slime Against Humanity.
This is the hinted at “any number in your deck” card from Maro’s teaser
