  2. When the creature enters the battlefield, Cloudstone Curio and Molten Echoes trigger.
  3. Resolve the Cloudstone Curio trigger, choosing to return nothing to your hand.
  4. Resolve the Molten Echoes trigger, creating a token copy of the generic mana cost creature.
  5. When the creature token enters the battlefield, Cloudstone Curio triggers, returning the nontoken generic mana cost creature from the battlefield to your hand.
