General Magic / Re: Converted Mana Cost on the Stack
« em: Janeiro 07, 2019, 09:33:19 am »So let me see if I understand this. If someone casts Green Sun's Zenith where X=1, Mental Misstep can't counter it but Spell Snare can?
d(^^d) bingo
When a spell has X in the cost, x = 0 for the purpose of calculating CMC.
The *ONLY* time X is not zero is when it is on the stack (though x could be zero there, too, if you case with x being zero, like casting Hangarback Walker for 0 to get a death trigger or something)
And the alternate value for X only exists on the stack. So if I cast Hangarback Walker X=10 and it resolves, my opponent can destroy it with a ratchet bomb with no counters because even though I CAST it with x=10 (so a 20cmc on the stack), on the.battlefield x=0
