Let me start by getting an overview of Legacy Dimir Tempo archetypes and the format meta changes.
There's one "Dimir Tempo" archetype in Legacy. Let me now check if there are sub-variants by querying the database for distinct Dimir Tempo archetypes, and simultaneously pull the winrate for the main archetype over the recent meta window.
There's only one "Dimir Tempo" archetype in Legacy. The UB family includes Dimir Delver and Dimir Ninjas which are tempo-adjacent variants. Let me pull winrates for all three alongside the recent meta window (post-Edge of Eternities, Aug 2025).
Here's the full breakdown of Legacy UB/Dimir tempo-style archetypes since Edge of Eternities (Aug 2025), the current meta epoch:
| Archetype | W | L | D | Win Rate | Sample Size |
|---|---|---|---|---|---|
| Dimir Tempo | 3192 | 2886 | 190 | 52.5% ✅ | 6,268 matches |
| Dimir Delver | 237 | 224 | 19 | 51.4% | 480 matches |
| Dimir Ninjas | 102 | 138 | 10 | 42.5% | 250 matches |
| Dimir Death's Shadow | 103 | 157 | 8 | 39.6% | 268 matches |
All figures exclude mirror matches.
🥇 Dimir Tempo is the clear winner at 52.5% winrate — and it's not particularly close. It also has by far the largest sample size (6,268 matches vs. ~500 or fewer for the others), making it the most statistically reliable result.
Key cards driving the archetype: Brainstorm + Force of Will + Thoughtseize + Orcish Bowmasters + Kaito, Bane of Nightmares.
Dimir Delver is the second-best tempo option at 51.4%, but has much lower representation. Ninjas and Death's Shadow are both clearly below the 50% threshold in this window.
