thorn of amathyst and Force of Will
Asked by skyb0rg 13 years ago
How would stuff like Thalia's ability affect spells like Commandeer?
landot, that is not correct. Sphere of Resistance effects alter the total cost, not the CMC. They do not make Brainstorm vulnerable to Spell Snare, for example, and the additional mana that must be paid is applied even if you are not paying the mana cost of the spell.

This is incorrect. The total cost of a spell is its mana cost OR alternate cost + any cost increasers - any cost reducers. In this case, the total cost for Force of Will will be paying 1 mana, exiling a blue card from your hand, and losing 1 life.

So how would those work with cycling? I don't think it alters that. Or does it?

Cycling is an ability, not an alternate casting cost. Since you aren't casting anything when you cycle a card, effects like Thalia, Guardian of Thraben and Thorn of Amethyst don't change anything about it.

Things like Thorn of Amethyst
and Thalia, Guardian of Thraben
alter the mana cost. They do not alter alternate costs; if a spell gives you access to an alternate cost, you don't have to pay the extra mana.
