3 rulings from Wizards of the Coast
- 5 October 2018You choose whether to sacrifice a permanent (and which one to sacrifice) while Vraska's first ability is resolving. No player may take actions between the time you choose which permanent to sacrifice and the time you do so.
- 5 October 2018If a permanent has {X} in its mana cost, X is considered to be 0.
- 5 October 2018Tokens that aren't a copy of something else don't have a mana cost. Anything without a mana cost normally has a mana value of 0.
