Cards

Gameplan

Rona reads “Whenever you cast an instant or sorcery spell, each opponent loses 1 life,” and she can be recast from the graveyard by discarding two cards, so she is effectively unkillable. The whole deck is a dedicated instant/sorcery control shell: counter the threats, kill what resolves, refill with card draw, and let every reactive spell ping the entire table. Across a normal control game you cast 25-35 instants/sorceries, which is 25-35 points of table-wide drain on top of your interaction — your answers ARE the clock.

This is a draw-go control deck, but the win path is explicit inevitability, not “wrath and hope”:

  1. Rona drain — the primary engine. Every counter/removal/cantrip you were going to cast anyway costs an opponent life.
  2. Recursion grind — Archaeomancer, Scribe of the Mindful, Mnemonic Wall, Mystical Teachings and flashback spells (Think Twice, Deep Analysis, Forbidden Alchemy) re-buy your spells, so you out-card the table while re-triggering Rona each cast.
  3. Big finishers — Gray Merchant of Asphodel, Corrupt, and Tendrils of Corruption convert your devotion/lands into large life swings to close, while Stream of Thought + Cathartic Adept provide a mill backstop.

Role Breakdown (with counts)

  • Lands: 39 — 9 Island, 9 Swamp, plus 21 nonbasics including UB duals (Contaminated Aquifer, Ice Tunnel, Dismal Backwater, Dimir Aqueduct, Dimir Guildgate, Murky Sewer, Waterfront District, Serpent’s Pass, Mistvault Bridge), fixers (Command Tower, Evolving Wilds, Ash Barrens, Crumbling Vestige), and utility (Halimar Depths, Mystic Sanctuary, Bojuka Bog, Mortuary Mire, Witch’s Cottage, cycling lands Lonely Sandbar/Barren Moor). The slightly high land count supports a control deck that wants to hit every drop and cast multiple spells per turn.
  • Ramp (mana rocks): 9 — Sol Ring, Mind Stone, Dimir Signet, Thought Vessel, Guardian Idol, Prismatic Lens, Dimir Cluestone, Star Compass, Fractured Powerstone. Lets you hold up answers while developing.
  • Card advantage: 11+ — dedicated: Brainstorm, Consider, Sign in Blood, Read the Bones, Night’s Whisper, Think Twice, Deep Analysis, Forbidden Alchemy, Mystical Teachings, Compulsive Research, Reckoner’s Bargain. Plus value creatures Augur of Bolas, Sea Gate Oracle, Mulldrifter, Crow of Dark Tidings.
  • Counters / permission: 14 — Counterspell, Mana Leak, Miscalculation, Condescend, Syncopate, Disdainful Stroke, Arcane Denial, Memory Lapse, Logic Knot, Disrupt, Spell Pierce, Exclude, Cancel, Phantom Interference.
  • Spot removal / interaction: 12 — Murder, Doom Blade, Cast Down, Bake into a Pie, Snuff Out (free!), Disfigure, Defile, Eaten Alive, Diabolic Edict, Geth’s Verdict, Vapor Snag, Tendrils of Corruption.
  • Mass wipe: 0 — commons-only Dimir lacks a true board wipe, so the deck compensates with a deep counter+edict suite, evasion-proof drain inevitability, and a heavy interaction density. Edicts (Diabolic Edict, Geth’s Verdict) act as pseudo-removal against hexproof/big threats.
  • Recursion / win finishers: Archaeomancer, Scribe of the Mindful, Mnemonic Wall (rebuy spells), Mystical Teachings (toolbox), Stream of Thought + Cathartic Adept (mill), Gray Merchant of Asphodel, Corrupt, Tendrils of Corruption (life drain finishers).

Key Synergy Lines

  • Flashback = double Rona triggers. Think Twice, Deep Analysis, and Forbidden Alchemy each get cast twice, draining twice.
  • Recur-and-recast loop. Archaeomancer / Mnemonic Wall return your best instant or sorcery; each recast pings the table again. With Mystic Sanctuary you can rebuy a counter from the top.
  • Gray Merchant rewards the heavy black pip count from your removal suite — often a 6-10 life swing that also gains you life to stabilize.
  • Hold-up turns. With a rock out, leave up Counterspell + a cantrip; if nobody bites, end-step Think Twice/Consider still advances the Rona clock.

Pilot Notes

  • Mulligan for 2+ lands and a rock or an early cantrip. You want to be casting spells every turn from turn 3 on.
  • Don’t hoard answers — every spell you cast is damage, so it’s fine to “waste” a counter on a marginal spell if you’re racing on the Rona clock.
  • Sequence drain finishers (Gray Merchant, Corrupt, Tendrils) for when one opponent is already low from accumulated pings.
  • Rona is recastable from the yard for “discard two cards” — bin excess lands/dead cards to bring her back; don’t over-protect her.
  • Bojuka Bog / Mortuary Mire / Mystic Sanctuary on relevant turns give graveyard hate and selection.

Weaknesses

  • No true board wipe. A wide aggressive go-wide board can outpace single-target removal; lean on edicts, counters, and chump-blocking value creatures, and race with drain.
  • Fast combo / explosive starts can get under draw-go; the soft counters (Mana Leak, Force-style) get worse late, so prioritize them early.
  • Lifegain decks dilute the drain clock — pivot harder to mill (Stream of Thought) and counter their engines.
  • Heavy graveyard hate blunts the recursion plan, but the Rona clock itself doesn’t need the yard.
