Essence of Slime

Whenever you play an activated ability, put a 1/1 slime token into play. Whenever you are dealt 3
or more damage in a turn, you may sacrifice all slime tokens to play a slime monster token with power and toughness equal to the number of slime tokens sacrificed. When a slime monster token is dealt damage and survives, sacrifice it
and put X 1/1 slime tokens into play where X is equal to the slime monsters power -1.
