Enchant creature
When enchanted creature dies, you draw three cards and you gain 3 life.

Flip a coin until you lose a flip or choose to stop flipping. Exile the top X cards of each player's library, where X is 1 plus the number of flips you won. You may play those cards until the end of your next turn, and you may spend mana as though it were mana of any color to cast those spells.
