Primordial Ooze

Creature - Ooze 1/1, R (1)
Primordial Ooze attacks each turn if able.
At the beginning of your upkeep, put a +1/+1 counter on Primordial Ooze. Then pay {X}, where X is equal to the number of +1/+1 counters on Primordial Ooze, or tap Primordial Ooze and it deals X damage to you.¹
The thick, moving mass from the beginning of evolution swallows and digests the animate and inanimate as it unthinkingly strives to continue its existence.
