Chalice of the Void
Color= Artifact Type= Artifact Cost= XX MR(R)
Text (MR): ~this~ comes into play with X charge counters on it. ; Whenever a player plays a spell with converted mana cost equal to the number of charge counters on ~this~, counter that spell.
To have it come into play with 3 counters, X must be 3, which means you have to pay

{3} or

mana. You pay twice of whatever value you want X to be. [Mirrodin FAQ 2003/10/01]
It only checks the number of counters on this card at the time the spell is being played. Changing the number of counters after that will not change the outcome. [Mirrodin FAQ 2003/10/01]
If it has zero counters on it, then it triggers for spells of cost

. [Mirrodin FAQ 2003/10/01]
It has to be in play at the end of the playing of a spell to trigger. If you sacrifice it during the playing of a spell, it will not trigger. [Mirrodin FAQ 2003/10/01]
Note - Also see Converted Mana Cost, Rule G3.25.
Note - Also see X Costs, Rule G24.1.
Hello, I was just wondering if you have a chalice with 3 counters on it and play tinker sacrificing the chalice to it, will the tinker resolve or not? On crystal keep, it says that if cotv is saced during the playing of the spell, it will not trigger. Does sacing it as part of the cc count as sacing it during the playing of the spell and thus nullify the trigger and allow the tinker to resolve? I found the crystal keep wording slightly confusing and am only asking for clarification. Thanks a lot.
