It's also a Normal monster that has a Pendulum effect, something that had never been seen before! During the End phase that this card is played in a Pendulum zone, you can target one face-up Spell/Trap Card on the field and destroy it. This, of course, includes other Pendulum Monsters. When this card was released, there were also tons of relevant face-up Spell and Trap cards in play in the metagame. Overall, this is a fairly good effect.
With Spellcasters a fairly viable archetype all of their own, it seemed this monster might have some potential. But, as more of the ARC-V sets were released, it quickly became outclasses. Still, in a vacuum, this isn't a bad monster at all. Spell & Trap destruction is certainly very splash-able and Pendulum Normal Monsters certainly would get better and better. Foucault’s Cannon also has a Pendulum Scale of 2, making it a great lower-end scale in a Pendulum-heavy deck.
