Cryptic Visions

my primary uncertainty regarding this build is whether to retain the spell snare or replace it with something like negate. whereas they are both selective counters, i find that in certain games i would prefer negate over the snare. it seems to be about a 50 50 instance. perhaps there is some better alternative to either. i must say i miss counterspell. however my favorite element to this deck is that with guile, remand becomes a 2 cost hard counter with draw and a commandeer effect! the main problem i have here is the conflict between av and spell snare and shackles with seat of synod.
