Karat, Gilded Soulwillow

Defender, Deathtouch
Whenever Karat, Gilded Soulwillow or another creature dies, put a colorless Gold artifact token with "Sacrifice this artifact: Add one mana of any color to your mana pool."
Whenever you sacrifice a gold token, you may pay {2}. If you do, return target creature card from your graveyard to your hand.
Who said money doesn't grow on trees.
