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, Monsoon Mage 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.

Rak, Leyline Prodigy enters the battlefield with an additional loyal counter on him for each instant and sorcery spell you've cast this turn.
+1: Until your next turn, instant and sorcery spells you cast cost less to cast.
-2: Ral deals 2 damage divided as you choose among one or two targets. Draw a card if you control a blue permanent other than Ral.
-8: Exile the top eight cards of your library. You may cast instant and sorcery spells from among them this turn without paying their mana costs.
