Now let me get the winrate data for the top contenders and also look at the most recent Showcase Challenge specifically.
Now I have everything I need. Let me also get the archetype overview for Energy in Legacy to get the correct ID.
Here is the full breakdown, @OskarSakol:
BEST DECK FOR GRINDING MTGO LEAGUES: Dimir Tempo
Dimir Tempo (Tamiyo + Orcish Bowmasters) is the undisputed grind deck of the current Legacy meta. It is the most-played archetype by a massive margin — 13.16% meta presence, 461 entries across 128 tournaments, and a solid 52.93% mirror-free winrate since mid-January. Its consistency, raw card quality, and ability to play both control and tempo roles make it ideal for leagues where you face a wide range of opponents. It also had 7 appearances in the recent Showcase Challenges (Jan–Mar), confirming it punches through competitive fields too. Key cards: Tamiyo, Inquisitive Student, Orcish Bowmasters, Force of Will, Fatal Push, Underground Sea.
BEST DECK FOR WINNING TOURNAMENTS: The answer splits depending on context.
For pure winrate, Azorius Stoneblade is the standout. Despite modest meta share (1.54% presence, 63 entries), it posted a stunning 62.67% mirror-free winrate across 256 matches — the highest of any notable archetype in the format. This is a small-sample outlier warning, but it is consistently in the top of that bracket. However, for raw Showcase Challenge top 8 representation since January, Oops! All Spells leads with 11 appearances, followed by Show and Tell and Energy at 9 each. The most recent Showcase Challenge (March 15, 2026) had Energy (3 copies), Dimir Tempo (5 copies), Show and Tell (3 copies), Oops! All Spells (3 copies), Mystic Forge Combo (3 copies), and Aluren among the top finishers, showing a genuinely diverse winner's bracket.
For paper and larger hybrid events, Energy (54.31% winrate, 5.98% meta share, top 8 presence in every Showcase since October) and Lands (55.17% winrate, 3.64% meta share) offer strong equity. Lands specifically has a high winrate for its volume, is resilient against disruptive strategies, and appears consistently in Showcase top 8s. If you want one "tournament winning" recommendation with broad data support: Energy is the best all-around deck to win events right now — it combines high presence, strong winrate, and consistent Showcase Challenge finishes across multiple events.
Summary table (Jan 15 – Mar 17, 2026, mirror excluded):
Archetype | Meta% | WR% | Showcase T8 (since Jan)
Dimir Tempo | 13.2% | 52.9% | 7
Energy | 6.0% | 54.3% | 9
Oops! All Spells | 4.9% | 50.6% | 11
Lands | 3.6% | 55.2% | 5
Doomsday | 3.5% | 54.5% | 1
Azorius Stoneblade | 1.5% | 62.7% | 0 (low sample)
