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.
