Go blank is maybe bad. It is useful vs. graveyard combos but most of the time the exile part is useless (and feels kinda rude) or even counterproductive is you have graveyard stealing I advice inscription of ruin instead. At least if opponent has no card it can still do stuff. Discard deck are fun. I advice for the batgod or one of tinybone (or tergrid but she is even harder to pull of than wastenot) to exploit further (liliana is okay as wincon).
