Morph
- Although turning a face-down creature with morph face up doesn't use the stack, Rattleclaw Mystic's triggered ability does use the stack, and players can respond to that ability. Notably, you can't turn Rattleclaw Mystic face up while casting a spell or activating an ability. You'll need to turn Rattleclaw Mystic face up and have its triggered ability resolve before you can spend that mana.
- Morph lets you cast a card face down by paying {3}, and lets you turn the face-down permanent face up any time you have priority by paying its morph cost.
- The face-down spell has no mana cost and has a mana value of 0. When you cast a face-down spell, put it on the stack face down so no other player knows what it is, and pay {3}. This is an alternative cost.
