Phyrexian Negator My big beat stick and easy enough to get out with the Aether Vial. Doesn't serve much pourpose opther then being a big warm body.
Why would you want to put a Vial on 3 counters? You other creatures are 1B, Vial on 2 seems like a much better choice.
Negator is something you want on the board first or second turn with ritual. Third or fourth turn it will probably be obsolete.
Also, the Dust to Dust has double W in it's cost AND needs 2 Artifacts to even be played.
You call it Fish, then why don't you run any strip effects?
I think this deck could use some serious tuning, the matchup vs. Staxx and random control seems very hard.
