Commentary
Obsidian Forge specifically looks at whether a creature was successfully sacrificed to reduce the key cost. If a card was prevented from being sacrificed or leaving play by an effect like Ward, the creature's ward token will be removed, but it will not reduce the cost to forge.
When resolving the ability of this card, "any number" can be treated as zero.
