Little King Trashmouth

At the beginning of your first main phase, add {r}
or {g} for each Raccoon you control.

Whenever you expend 4 you gain 3 life.
(You expend 4 as you spend your fourth total
mana to cast spells during a turn.)

Whenever you expend 8, exile the top two
cards of your library. Until the end of your
next turn, you may play those cards.
