Mono-Black Midrange Grind

A mono-black midrange deck that uses cheap deathtouch bodies, hand disruption, and efficient removal to survive the early game, then snowballs card advantage with Preacher of the Schism, Phyrexian Arena, and Massacre Girl, Known Killer while closing with evasive threats like Unstoppable Slasher and Abyssal Harvester.

• Deep-Cavern Bat and Duress strip the opponent's best cards while giving you a body and information.
• Preacher of the Schism draws a card every time it attacks if you control a creature with deathtouch (Deep-Cavern Bat, Tinybones, Unstoppable Slasher, Massacre Girl) — with two deathtouchers on board it becomes a repeatable two-for-one.
• Massacre Girl, Known Killer turns every deathtouch creature into a card-drawing machine whenever it deals combat damage, and her -1/-1 shrink makes your 1/1 deathtouchers win any block.
• Tinybones, Bauble Burglar punishes the opponent for the discard caused by Duress and Deep-Cavern Bat, effectively making your disruption cantrip.
• Unstoppable Slasher is nearly unkillable (it returns if it would die) and halves the opponent's life total when it connects, turning chip damage into a lethal clock.
• Phyrexian Arena guarantees a fresh card every turn so the deck never runs out of gas.

Keep any hand with 2-4 Swamps, at least one early interaction spell (Duress, Bitter Triumph, Shoot the Sheriff, Hero's Downfall), and ideally one engine piece (Preacher of the Schism, Phyrexian Arena, Massacre Girl) or a resilient threat (Unstoppable Slasher). Mulligan hands with fewer than 2 lands, more than 5 lands with no action, or hands with zero removal against unknown opponents.

• Early: Lead with Duress to strip their best card, then deploy Deep-Cavern Bat to disrupt and start chipping. Hold Bitter Triumph / Shoot the Sheriff / Hero's Downfall for the first real threat. Trade your deathtouchers profitably.
• Mid: Resolve Preacher of the Schism or Phyrexian Arena to pull ahead on cards, then stack Massacre Girl, Known Killer with your deathtouch team to convert every attack into card advantage while grinding down their board with removal.
• Late: Unstoppable Slasher and Abyssal Harvester provide resilient, evasive pressure that is very hard to answer. Fountainport lets you cash in spare mana for extra cards, and continuous Arena/Preacher draws simply bury the opponent.

• Board wipes clear your creature base and turn off Preacher and Massacre Girl.
• Enchantment removal answers Phyrexian Arena, and graveyard hate stops Abyssal Harvester.
• Very fast aggro can race you if you stumble on early removal; heavy lifegain decks can outlast your drain-free clock.
• The deck leans on a few key engines, so protecting Preacher and Massacre Girl with careful blocking and removal sequencing is essential.
