Rotgut

Rotgut enters the battlefield with 3 Decay
counters on it. Whenever Rotgut takes damage, prevent it and remove a Decay counter instead.
When Rotgut has no Decay counters, sacrifice it.
{1}{b}{b}: Rotgut gets +3/+3 and gains menace
until end of turn. Put a Decay counter on Rotgut.
With a bloated, bile-infested stomach, its stench is the
first sign of the approaching Rotgut.
