Narset's When it attacks trigger and X mana costs?
Asked by Dk_Donuts1 9 years ago
So when you attack with Narset, Enlightened Master, you exile the top 4 cards of your library and then play noncreature spells without paying their mana costs. So my question is, if you were to exile the top 4 with Narset, and got a Crater's Claws, what would (X) be? Can you say how much (X) is or is it only 1 by default?
The converted mana cost is one, but any case where an X spell wasn't regularly cast means it equals 0.

@vishnarg: CMC isn't relevant here. Did I miss something?

Oh, my bad. I thought he asked a question about if Craters Claws could work with Narset for it's CMC.

Basically, I read Narset wrong. Disregard my answer.

Always check the Gatherer rulings before asking a question.
9/20/2014: If the card has X in its mana cost, you must choose 0 as the value for X when casting it.
When you cast a spell with
in its mana cost, you declare the value of 
as you cast it, but only if you are paying that spell's mana cost. If you are casting it for an alternate cost, you don't get the option to decide 
, and 
defaults to zero.
