Kanna, Tiamat's Servant

Haste
At the beginning of combat, create a 0/1 black
creature token named Servant. It has "This
creature must attack if able and must be blocked
by two or more creatures if able." Exile this
token at the beginning of the next end step.
Whenever Kanna, Tiamat's Servant deals combat
damage to a player, create two colorless artifact
tokens named Gold. It has "Sacrifice this artifact:
Add one mana of any color."
