MAGIC: THE GATHERING
, Sacrifice a nontoken artifact: Put a 1/1 blue Thopter artifact creature token with flying onto the battlefield. You gain 1 life.
Sword of the Meek combos with Thopter Foundry in a big way. Every time you sacrifice the Sword to the Foundry you get a 1/1 which triggers the Sword to return again. So basically for every mana you spend you get a 1/1 flyer and gain a life. Not bad.
