Official rulings
- For spells with {X} in their mana costs, use the value chosen for X to determine the spell's mana value. (2021-03-19)
- An ability that triggers when a player casts a spell resolves before the spell that caused it to trigger. It resolves even if that spell is countered. (2021-03-19)
- Alternative costs, additional costs, and cost reductions don't change a spell's mana value. Its mana value is still based on its mana cost. (2021-03-19)
