Equilibrium

Enchantment, 1UU (3)
Whenever you cast a creature spell, you may pay {1}. If you do, return target creature to its owner's hand.¹
Seek balance in all things-as long as the scales are weighted in your favor.
-Vodalian saying
Illus. Don Hazeltine

Gatherer Card Rulings [Nov 2009]

• 4/1/2008: A "creature spell" is any spell with the type Creature, even if it has other types such as Artifact or Enchantment. Older cards of type Summon are also Creature spells.
• 8/1/2008: The ability is put on the stack immediately after you cast a creature spell, whch means the creature that spell will become won't be a legal target.
• 8/1/2008: The ability will still resolve even if the spell that triggered it gets countered.
