Here's the full breakdown! Note: "Dimir Frog" didn't show in the meta report (very low presence), so I'll focus on the three meaningful Dimir archetypes. Dimir Delver and Dimir Ninjas are essentially fringe with only 7 entries each.

🃏 Legacy Dimir Tempo Builds — Full Breakdown (Aug–Oct 2026)

The Legacy Dimir space has three meaningful builds right now, all sharing a UB shell but with distinct win conditions and philosophies.

🔵⚫ Shared Core (all builds)

Every Dimir deck runs this foundation:

• Force of Will x4 | Brainstorm x4 | Ponder x3–4
• Thoughtseize x3.5–4 | Fatal Push x3–3.3
• Undercity Sewers x1 (cantrip land)
• Underground Sea + Polluted Delta + fetchland suite
• Wasteland (most builds, 70–100%)

1️⃣ Dimir Tempo (The Flagship)

Meta share: #1 Legacy archetype at 7.77% presence | 161 entries across 78 tournaments
Winrate: 53.2% (excl. mirror, 680 matches)

The Plan: Kaito + Orcish Bowmasters pressure, tempo out with Daze and Wasteland, close with Murktide or Nethergoyf.

Key cards (beyond core):

Identity: Classic permission + pressure. Daze + Wasteland = soft mana denial. The flex slots split between Murktide (raw power) and Bilbo (evasive/thieving).

Sideboard highlights: Force of Negation (99%), Consign to Memory (98%), Barrowgoyf (84%), Hydroblast (80%), Massacre (71%)

2️⃣ Dimir Bilbo (All-In on Bilbo)

Meta share: 2.83% presence | 60 entries across 36 tournaments
Winrate: 52.5% (excl. mirror, 242 matches)

The Plan: Maximizes Bilbo, Thief in the Night (97% presence, ~3.5 copies) alongside Moonshadow and Nethergoyf for a more aggressive, evasive threat package.

Key differences vs base Tempo:

Identity: Leans into Bilbo + Moonshadow as its primary threat engine. Bauble + Nethergoyf = graveyard synergy. Orcish Bowmasters moves to the SB as a reactive tool rather than a proactive one. More linear and aggressive than the base build.

Sideboard: Consign (100%), Force of Negation (90%), Orcish Bowmasters (86%), Nihil Spellbomb (64%), Hydroblast (59%), Bloodchief's Thirst (45%)

3️⃣ Dimir Midrange (Slower, Grindier)

Meta share: 1.59% presence | 31 entries
Winrate: 48.9% (excl. mirror — underperforming)

The Plan: Less Wasteland/Daze reliance, more raw card quality and value engines. Plays fewer tempo elements in favor of longer-game resilience.

Key differences:

• Wasteland drops to only 70% presence (vs 99%+ in Tempo)
• Daze at only 52% — this is not a tempo deck
• Tamiyo at 67% as the primary threat (vs Kaito/Bowmasters at ~48%)
• Flow State at 85% — heavy cantrip density
• More basic lands (Island at 88%), more conservative mana base
• No clear "finisher" package — feels like a control-midrange hybrid

Identity: Closer to a draw-go blue-black control style. The results tell the story: 48.9% winrate suggests it's struggling in the current meta vs the more proactive builds.

📊 Head-to-Head Summary

🔑 TL;DR

• Dimir Tempo is the clear #1 Dimir (and #1 Legacy) archetype — flexible threat mix with Kaito/Bowmasters core
• Dimir Bilbo is a legitimate alternative for players who want a more aggressive, synergy-driven version centered on Bilbo + Moonshadow + Nethergoyf
• Dimir Midrange is underperforming right now and not recommended at 48.9% WR
• The key fork: Kaito/Bowmasters package (Tempo) vs Bilbo/Moonshadow/Bauble package (Bilbo build)
