This deck needs Grave Pact. Sacrifice effects are amazing, especially when they come from an often-activated trigger. Also, you know that your name is only niv-mizze, right? There's a t after the final 90 degrees to finish the name. The =1 is gravy as well.
EDIT: and it's supposed to be (Z-V), not (N-V). (N-V)90 is zig.
lol. Also, have you considered Vicious Shadows or Time Stretch. The former is really good in this list (note: you can deal the damage to any player, so when a player sacs to thrax, you can have another player take the shadows damage), while the latter is the most obnoxious card in blue and should go in practically every deck running it (even though I hate it).
