Strategy
Classic Dimir attrition: answer everything, then let a protected planeswalker grind the game to dust. A dense suite of counterspells and cheap removal keeps the board clean while card-advantage engines (Read the Bones, Cruel Truths, Bad Deal, Phyrexian Gargantua) refuel you past every trade. Kaito, Bane of Nightmares is the win condition — ninjutsu him in off any of the deck’s many cheap flyers, then ult toward inevitability, with the surveil/mill creatures feeding Consuming Aberration as a backup finisher. Three sweepers (Languish, Malicious Eclipse, Deadly Cover-Up) reset aggressive boards. This refinement pass kept the proven core and tightened the edges: added Stock Up (the format’s premier dig-for-answers selection, now untruncated and correctly valued) and Into the Flood Maw (1-mana flexible bounce that resets hexproof threats and re-enables ninjutsu), upgraded removal with the owned-rare Black Sun’s Twilight (scalable -X/-X that also reanimates late) and Tragic Slip (a 1-mana -13/-13 the instant any creature trades — trivial in this trade-heavy shell), and slotted Fatal Fissure — a cheap instant earthbend payoff that turns a removal trigger into a 4/4 land-body, sneaking ramp plus a blocker into the control plan. Cuts were the narrowest/most redundant filler: Cruel Cut (destroy power ≤2), Diresight (sorcery-speed clone of instant-speed Cruel Truths), Opt (weakest cantrip), Curious Cadaver (clunky Clue-dependent recursion), and Buzz Bots.
Upgrade path
LAND REVAMP 2026-07-11: manabase rebuilt to kill taplands (cut guildgates/temples/gainlands); now runs shock + verge (+painland in Brawl) untapped duals + basics. Land crafts this pass: Underground River. Zero rare/mythic SPELL crafts — every rare and mythic in the 99 (Languish, Deadly Cover-Up, Consuming Aberration, Raven Eagle, Bitterbloom Bearer, Riddlemaster Sphinx, Dragonlord Silumgar, Junji, Demon of Loathing, Wan Shi Tong, Sidisi, Postmortem Professor, Drag the Canal, and the newly added Black Sun’s Twilight) is already OWNED (own>=1), so rare discipline holds — no wildcards spent. The other adds this pass are commons/uncommons (Stock Up uc, Into the Flood Maw uc, Tragic Slip c, Fatal Fissure uc), all freely owned. Manabase is all-owned nonbasics + basics; no shock added (none approved for this pair). All 99 verified against the pool DB: owned, brawl-legal, UB color identity, singleton respected, 37 lands. Upgrade path if Mik spends wildcards later: swap a couple of the tapped basic-fixers (Dimir Guildgate, Serpent’s Pass, Murky Sewer) for new untapped UB duals once printed/owned — singleton blocks dupes of Watery Grave/Gloomlake Verge. | Land audit 2026-08-23: +2 lands (cut Tragic Slip, Calamitous Tide).

Ideal build (upgrade target)
Ideal is a premium Dimir attrition build: best-in-class counters (Cryptic Command, Archmage’s Charm, Drown in the Loch, Three Steps Ahead), best cheap removal (Go for the Throat, Fatal Push, Cut Down, Bloodchief’s Thirst) and real sweepers (The Meathook Massacre, Toxic Deluge, Crux of Fate), plus top card-advantage (Search for Azcanta, Memory Deluge, Dig Through Time, Sheoldred as a punishing engine). Wincons layer Kaito, Liliana of the Veil, and inevitability threats over Consuming Aberration. Manabase goes all-untapped with creaturelands (Creeping Tar Pit, Hall of Storm Giants) + Otawara + Castle utility. Top craft priorities: Sheoldred, the Apocalypse (mythic), The Meathook Massacre (mythic), Cryptic Command (rare), Liliana of the Veil (mythic), Creeping Tar Pit (rare).
Crafts to reach the ideal: 23 (3 mythic, 18 rare, 2 uncommon)
- Mythic: Crux of Fate, Liliana of the Veil, The Meathook Massacre
- Rare: Archmage’s Charm, Baleful Mastery, Castle Locthwain, Castle Vantress, Creeping Tar Pit, Cryptic Command, Darkslick Shores, Dig Through Time, Drowned Catacomb, Extinction Event, Hall of Storm Giants, Hullbreaker Horror, Memory Deluge, Otawara, Soaring City, Search for Azcanta // Azcanta, the Sunken Ruin, Shipwreck Marsh, Sign in Blood, Toxic Deluge
