Slaad Birth

This card enters the battlefield with three
incubate counters on it. On your upkeep, remove
an incubate counter from this card. If there are
no incubate counters left on this card, destroy
target creature or planeswalker and create a black
1/3 Slaad Tadpole creature token with
Deathtouch, then sacrifice this card. If you chose
a planewalker, the Slaad Tadpole token creature
is green as well. —— You may have any number
of Slaad Birth cards in a deck.
