If you're able to play this, it's dealing at least 4 damage, probably 5+ most of the time, and with two good keywords. It's fantastically efficient. Definitely worth the slots in a Wolverine deck, since basic Colossus is a good ally. It's a bit more of a stretch to run a Colossus deck with the Wolverine ally, as the cost can be tough to pay and it of course locks you into Aggression.

If you're playing Piotr and Logan decks at the same table, absolutely put Fastball Special in both. Let's go, bub!
