Molroob, Mother of Ooze

Whenever a non-ooze creature enters the
battlefield under your control create a 1/1 green
ooze creature with soulbond. It gains "This
creature attacks and blocks only with its paired
creature" and "sacrifice this creature at end of
turn if it isn't paired with a non-ooze creature".
Whenever an ooze receives lethal damage, Molroob
deals 1 damage to any target.
