Master of the Inner Flame

Haste
When Master of the Inner Flame enters the battlefield, you may reveal cards from the top of
your library until you reveal a spell card. You
may cast this spell as if it had convoke. If you tap Master of the Inner Flame to help cast that spell,
you may have it deal 4 damage to target creature
or player. Then, shuffle all non-cast revealed
cards into your library.
