My fastest ever standard mythic (#558) with "no-rare budget mono Black" deck.

Used this deck to push through Diamond BO3:

Budget B Aggro

Deck 16 Swamp 4 Gatekeeper of Malakir 1 Heraldic Banner 4 Cult Conscript 4 Anoint with Affliction 4 Scorn-Blade Berserker 4 Blot Out 4 Faerie Dreamthief 4 Deep-Cavern Bat 4 Forsaken Miner 4 Thought-Stalker Warlock 4 Mudflat Village 3 Defiled Crypt // Cadaver Lab

Sideboard 3 Dreams of Steel and Oil 3 Final Vengeance 1 Nowhere to Run 3 Leyline of the Void 2 Heraldic Banner 3 Nowhere to Run

I had seen this list in this sub and tried it out, it somehow gets there! Played also other brews, so not sure about overall winrate. Final push was 8-2. I mainly draft, so for me hitting mythic that early in the season probably means this is legit and easy to craft.
