Refraction Trap
Refraction Trap {3}{W}
Instant - Trap
If an opponent cast a red instant or sorcery spell this turn, you may pay {W} rather than pay Refraction Trap's mana cost.

Prevent the next 3 damage that a source of your choice would deal to you and/or permanents you control this turn. If damage is prevented this way, Refraction Trap deals that much damage to target creature or player.
