Another Idea

I like the idea behind Arbiter and Ghost Quarter but other than that, this doesn't seem very "fish" like. You have minimal disruption. While the aggressive base is decent, some card choices seem mediocre. Invisible Stalker seems lame without some Swords in there. Grand Abolisher or Fiend Hunter would be pretty sick though, as one provides decent disruption, and the other is a good tempo shift.

Just my two cents....not sure if I am completely off here or not. Let me know what you think!
