Mainboard (60)
Goblins is an aggressive tribal deck that wins by curving Goblin Lackey into Goblin Warchief and Goblin Piledriver, then closing with Siege-Gang Commander or Goblin Ringleader refueling the hand. Your primary plan is to land a Phyrexian Dreadnought via Stifle as quickly as possible and protect it, since a 12/12 trampler ends the game before their go-wide strategy can overwhelm you. Blue Elemental Blast comes in to counter their key spells and permanents — particularly Goblin Warchief and Goblin Piledriver — and to answer their sideboard Pyroblasts. Annul handles Naturalize out of their board (which threatens your Stifle counter strategy if they try to target triggers) and their artifact-based threats. Hibernation is a one-sided board wipe that returns all red creatures to hand for a tempo-killing two mana, giving you a clean reset if they've assembled a threatening board before your Dreadnought arrives.
This is a pure mirror match where both players are trying to resolve a Phyrexian Dreadnought by stifling the sacrifice trigger or using Vision Charm to phase it out, while countering the opponent's attempts to do the same. Annul is brought in as cheap, hard countermagic that answers both Stifle and Vision Charm without requiring the untap step, giving you an edge in the counter war over key combo pieces. Brain Freeze comes in as an alternate win condition — in a counter-heavy game with lots of instants and sorceries being cast, a timely Brain Freeze post-storm can end a stalled game. Daze is cut because both players are likely to play around it by holding basic Islands, making it a dead card in longer counter battles, and the weaker cantrips (Opt, Misdirection) are trimmed to streamline your interaction density. The game will be decided by who resolves a Dreadnought first and who can protect it through the opposing stack of Stifles and Counterspells.
Mono-Black Midrange's primary axis against you is relentless hand disruption — Duress, Cabal Therapy, Ravenous Rats, and Hypnotic Specter all threaten to strip the Stifle or Vision Charm you need to land a Phyrexian Dreadnought cleanly. Dodecapod punishes their targeted discard directly: if they name it with Cabal Therapy or force you to discard it via Hypnotic Specter, it enters the battlefield as a 5/5, creating a genuine lose-lose for them. Annul answers Cursed Scroll before it can dominate a topdecking war, and post-board it stops Engineered Plague or Dystopia from dismantling your setup. Tsabo's Web neutralizes their utility lands — Wasteland can no longer blow up your Islands, Mishra's Factory can no longer animate and attack, and Spawning Pool loses its regeneration activation. Daze is trimmed because Dark Ritual lets them play through it at instant speed, and the remaining cuts are your weakest cantrips; your core engine of Stifle, Vision Charm, and hard counters stays intact to protect a fast Dreadnought.
