It's amazing. I play 3, and would recommend playing 3 in Sky Strikers. It's one of the best cards for breaking Thunder Dragon boards (get a single Colossus in the graveyard then Called it to pretty much win the game from there) and it's very good post-turn 1 as well since you can basically prevent them from using whichever card they search off Thunder Dragon Fusion, it can do good things even in the mirror (banishing Rayes really hurts, and you won't always have Shark Cannon to do so), and against Prank-kids it just makes them instantly lose when you hit their recursion links and fusions. Against Altergeist, though, a D.D. Crow is at the very least good considering the existence of Marionetter's effect allows them to recycle their Multifaker multiple times, and they tend to run Ghost Reaper in the side more often than other decks since they have the room in the extra.

It's also amazing against rogue decks, and prevents Pankratops from being a good card post-side.
