Calice du vide

Text:

Rulings:

• 3/16/2018 A mana cost of <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=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> means that you pay twice X. If you want X to be 3, you pay <img src="/Handlers/Image.ashx?size=small&amp;name=6&amp;type=symbol" alt="6" align="absbottom" /> to cast Chalice of the Void.
• 3/16/2018 The number of counters on Chalice of the Void matters only at the time the spell is cast. Changing the number of charge counters on Chalice of the Void after a spell has been cast won’t change whether the ability counters the spell.
• 3/16/2018 If there are zero charge counters on Chalice of the Void, it counters each spell with a converted mana cost of 0. This includes face-down creature spells cast with morph’s alternative cost.
• 3/16/2018 Chalice of the Void has to be on the battlefield at the end of casting a spell for the ability to trigger. If you sacrifice Chalice of the Void as a cost to cast a spell, its ability can’t trigger. However, if it leaves the battlefield once its ability has triggered, that ability will still counter the spell.
