Yusri, Fortune's Flame

Flying
Whenever Yusri, Fortune's Flame attacks,
choose a number between 1 and 5. Flip that
many coins. For each flip you win, draw a card.
For each flip you lose, Yusri deals 2 damage to
you. If you won five flips this way, you may cast
spells from your hand this turn without paying
their mana costs.
