Flaring Pain

Spells and abilities that replace or redirect damage are not affected by this card.

The "damage can't be prevented" statement overrides all forms of preventing damage. Damage prevention spells and abilities can still be cast and activated, they just don't do anything.

To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.
