If I cast a spell with X in its cost, such as torment of hailfire, using bolas’ citadel, can I choose to pay life for the value of X? Or will X inherently be 0? Thanks!
Whenever you pay an alternate cost to cast a spell, such as with Bolas’s Citadel, you can’t choose any value for X in the mana cost of the spell since you’re not paying the mana cost. In all of these cases, X is forced to be 0 and so Bolas does a pretty poor job of making these spells do anything.
