Assuming Wolverine and Deadpool fight, Team 2 takes this. I say that because the Wolverine/Deadpool fights are usually pretty even, but as WS says, Deadpool has the better skill with a sword. I'd give him a small majority.
Slade vs. Creed...Slade's healing factor is far less than either of these other three. He'd have to be virtually perfect against a stronger and faster opponent. I don't think he takes a majority in that fight.
