Nullstone Gargoyle

Artifact Creature - Gargoyle

Flying
Whenever the first noncreature spell of a turn is cast, counter that spell.

Nullstone absorbs and dampens most forms of magical energy, as well as light, sound, and heat.

4/5

2005-10-01 If another spell is cast in response to the first spell, Nullstone Gargoyle doesn't affect that second spell.
2005-10-01 Nullstone Gargoyle cares about the first noncreature spell cast during a turn, not the first one it "sees." If a noncreature spell was cast before Nullstone Gargoyle entered the battlefield, it won't counter the next one.
