Ruin Splicer

When Ruin Splicer enters the battlefield, if life
wasn't paid to cast it, create a 3/3 colorless
Golem artifact creature token.
Golem you control have Menace.
{b}, sacrifice an artifact: Put two -1/-1 counters
on target creature. If that creature would die this
turn, exile it instead, and it's controller gets a
poison counter.
