A while back I saw a grixis countertop deck and found it to be awesome. I think it could be viable. Here is a rough draft to get the conversation going, I leave out lands as there are many better than I at land lists:
1cc
4x Lightning bolt
4x top
3x discard
4x brainstorm

2cc
3x counter balance
4x daze
4x hymn

3cc
4x rift bolt
2x ensnaring bridge

4cc
4 abyssal persecutor
