I have been jumping back and forth between Miracle, Stoneblade, and Grixis Tempo lately and I think Lightning Blade is what I will settle on. I am not entirely sold on Grim Lavamancer yet because I want to ensure GY food for Snapcaster, Moorland Haunt, and Academy Ruins. I think StP and Bolt are both superior to Grim in a Blade shell and having 8-9 (EE) removal spells + SFM, Jitte, and Batterskull should be enough to secure aggro matchups. I feel like Grim is going overboard. Is he necessary against BUG, Jund, Gobs, and DnT?
