Effects that increase or reduce the cost to cast a spell don’t affect that spell’s converted mana cost.

For spells with X in their mana costs, use the value chosen for X to determine if the spell’s converted mana cost is even or not. For example, your opponent could cast Endless One (with mana cost X) with X equal to 5, but not with X equal to 6.

For creatures on the battlefield with X in their mana costs, the value for X is 0. Mistcutter Hydra (a creature with mana cost XG) could block, but Endless One could not.
