Rulings:

• 8/25/2015 Effects that increase or reduce the cost to cast a spell don’t affect that spell’s converted mana cost.
• 8/25/2015 For spells with <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in their mana costs, use the value chosen for X to determine if the spell’s converted mana cost is even or not. For example, your opponent could cast Endless One (with mana cost <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" />) with X equal to 5, but not with X equal to 6.
• 8/25/2015 For creatures on the battlefield with <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in their mana costs, the value for X is 0. Mistcutter Hydra (a creature with mana cost <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=G&amp;type=symbol" alt="Green" align="absbottom" />) could block, but Endless One could not.
• 8/25/2015 The converted mana cost of a face-down creature spell or a face-down creature is 0. Void Winnower will stop face-down creature spells from being cast and face-down creatures from blocking.
• 8/25/2015 Yes, your opponent can’t even. We know.
