One of the creatures with mana value 0 must be in your hand with the other on the battlefield.

  2. Rendmaw triggers, causing each player to create a tapped 2/2 Bird creature token.
  3. When the Bird enters the battlefield under your control, Cloudstone Curio triggers, returning a nontoken creature with mana value 0 from the battlefield to your hand.
  4. Resolve the creature spell cast in step 1.
