Drowning

I have some doubts about this deck but I belive its cool... My major concern lies in the sb... The only card Im sure about is mold shambler. The rest is heretic for card drawing (but its not that powerfull without cards like whispersilk cloak and such...), vines for protection, hive mind against decks that play a lot of instants and sorceries (since I play almost none) and winged coatl because its practicaly the only removal I have access to within these 2 colors... If anyone has different suggestions (mostly to sb) please post them...
