If there are additional costs to cast a spell, or if the cost to cast a spell is increased by an effect (such as the one created by Thalia, Guardian of Thraben’s ability), apply those increases before applying cost reductions. (2015-11-04)
The cost reduction can apply to alternative costs such as evoke costs. (2015-11-04)
If a spell you cast has {X} in its mana cost, you choose the value of X before calculating the spell’s total cost. For example, if that spell’s mana cost is {X}{R}{G} and you’ve chosen red and green, you could choose 5 as the value of X and pay {3}{R}{G} to cast the spell. (2015-11-04)
