Karn vs Shadehawk?

Actually, Takato, you don't know that Shadey's weapon is the ultimate. First of all, he started with it, so it can't count as ultimate because there's no competition. Secondly, Webrunner could easily put in, like, a Black Bow or something. ...which is rather likely.

And I'd vote the sisters for that. Although Poseidon being summoned would wipe the floor with the entire enemy party, by CMC rules.
