One ruling from Wizards of the Coast
- 27 January 2026To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as affinity for artifacts). The mana value of the spell remains unchanged, no matter what the total cost to cast it was.
