yeah, MirariKnight has really big point, if you want to use FoW, then use Pact of Negation. However from my experiences with belcher combo deck. I dont use any protection cards exept  Needle, Explosives and Duress, Thoughtsieze. About 2 moths ago when i am playin against goblins, i am drawing cards with Manamorphose and i drew 2 Guttural Response's. So i hate them:) And you said about your meta is mostly aggro, so you wont need any counterspell i think.

i think no. bec, you dont need it.
Just think, on your turn you are saying, come on boy, we are going to win this game, then you draw FoW.. so?
Or you cast Ad Nauseam, then draw second Ad Nauseam, and again you face with fow.. nope..

And i can suggest you some improvements
for example Yawgmoth's Bargain. Do you really need that? or gifts, academy.. Actullay gandalf has a lot of points. but i think  Needle and Explosives are really necessery, if you cant start storm early you will really need these.

Maybe you can use these changes, just a suggestion

-1 Inkwell Leviathan(never tried, i am not sure, but i wont want to draw it)
-1 Mind's Desire
-1 Cabal Therapy
-1 Necropotence(ive never tried but i dont like this card:)
-1 gifts(not good enough for this deck)
-1 Yawgmoth's Bargain
-1 Necropotence

+3 Chrome Mox
+1 Echoing Truth
+2 Thoughtseize

+1 Merchant Scroll
+1 Wheel of Fortune (not sure about these two.. but can be nice:D who knows)


and land base can be like

1 Bloodstained Mire
4 Flooded Strand
1 Island
4 Polluted Delta
2 Swamp
2 Underground Sea
1 Volcanic Island

like galdalf said, you need more fetch lands. and if u dont have you can use 2Watery Graves instead of underground seas

i'm working on a deck fast draw/discard.. and i have sth like that

cratures
4 hypnotic specter
2 shadowmage infiltrator
2 avatar of will

spells
4 hymn to tourach
4 Duress
3 cabal therapy
1 persecute
4 brainstorm
3 peek
2 unearth
4 diabolic edict
4 sudden death

using 19 lands

sidebord
1 cursed totem
1 perish

what should i do for it? any ideas?
but i'm not using moxes, demonic vsvs..
thanks
