Underworld Bartering

Return up to three creature cards from your
graveyard to your hand.
If you are the Despot, you may sacrifice a
creature, if you do, put one of those creature
cards onto the battlefield and lose life equal
to it's converted mana cost.
Surface factions refuse to trade with the Ukuru,
so it is fortunate for them that they have found a
partner with whom to conduct business without gold.
