Ral, Monsoon Mage // Ral, Leyline Prodigy

Instant and sorcery spells you cast cost less to cast.
Whenever you cast an instant or sorcery spell during your turn, flip a coin. If you lose the flip, Ral deals 1 damage to you. If you win the flip, you may exile Ral. If you do, return him to the battlefield transformed under his owner's control.
