Bloodstained Mace

Bloodsoak — When Bloodstained Mace enters the battlefield, you may sacrifice a creature, if you do,
put a number of blood counters on it equal to
that creature's power.
When you equip Bloodstained Mace, create a 1/1 Goblin token for each blood counter on it.
Equipped creature gets +2/+2.
