If I resolve the “Action:” on Obsidian Forge (WC 025) and choose to destroy a warded creature, will that creature reduce the cost to forge that key?

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 Obsidian Forge, "any number" can be treated as zero.
