Spawnbroker

Creature - Human Wizard 1/1, 2U (3)
When Spawnbroker comes into play, you may exchange control of target creature you control and target creature with power less than or equal to that creature's power an opponent controls.
The trick isn't setting up the bad trade. It's making each side think it got the better deal.
