- If an opponent casts a spell with {X} in its mana cost, use the value of X that was chosen when it was cast to determine its mana value.
- A spell's mana value is determined only by its mana cost. Ignore any alternative costs, additional costs, cost increases, or cost reductions.
- The mana value of a split card not on the stack or a fused split spell on the stack is determined by the combined mana cost of its two halves. Otherwise, while a split card is on the stack, its mana value is determined by the mana cost of the half that was chosen to be cast.
