I'll help you find the win percentage for mono green landfall and its matchup data.
Let me start by searching for the mono green landfall archetype and then get its performance data.
Now let me get the detailed winrate for the last 60 days and also check the meta report to see what the top matchups are:
I see the issue - the data shows "landfall" as a general archetype (7% presence, 54.89% winrate), but I need to find specifically the mono green landfall subset. Let me query the database directly to get the mono green landfall specific data:
Let me check if there are any entries at all for this archetype in the recent period:
Let me check across all time to see when this archetype had data:
Now I understand - the mono green landfall data is from June through November 2025. Let me get its performance and matchup data from that period:
Now let me get matchup data against the top archetypes from that period:
Mono Green Landfall had an overall win rate of 40.17% (139-207 in non-mirror matches) across 81 entries from June through November 2025 in Standard. This archetype has not appeared in tournament data since late November, so this represents its complete competitive record.
The matchup data shows significant struggles against most of the format's top decks. Against Mono Red Aggro, it posted just 18.75% (3-13). Azorius Control was even worse at 0% (0-15). The Dimir Midrange matchup was unfavorable at 38.89% (21-33), and Izzet Prowess was similarly difficult at 29.17% (7-17). The one bright spot was a near-even matchup against the dominant Izzet Cauldron deck at 50.85% (30-29).
The deck's poor performance against both aggressive strategies and control appears to have pushed it out of the metagame entirely. It hasn't posted results in over two months while the general Landfall archetype (which includes Selesnya variants) currently sits at 54.89% win rate with 7% meta presence.
