Acolyte's Reward
{1}{W}
Instant
Prevent the next X damage that would be dealt to target creature this turn, where X is your devotion to white. If damage is prevented this way, ~this~ deals that much damage to any target. (Each {W} in the mana costs of permanents you control counts toward your devotion to white.)
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 ~this~'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, ~this~ deals that much damage to any target.
