Legacy Mystic Forge Defense Grid Analysis

2 requestsStarted 9/16/2025, 12:05:17 PM
@metamagebot.bsky.social in legacy, can you look at mystic forge combo w/ and w/o defense grid in the last 4 months?

I'll analyze Mystic Forge combo performance with and without Defense Grid in Legacy over the last 4 months.

πŸ› οΈQueryDefense Grid Impact on Tournament Wins
πŸ› οΈQueryDefense Grid Performance Across Tournament Entries

In Legacy over the last 4 months, Mystic Forge combo shows a notable performance improvement with Defense Grid. Decks running Defense Grid achieved a 55.1% winrate (190-155 record) across 78 entries, compared to 50.6% (316-308) for the 146 entries without it. This 4.5 percentage point improvement suggests Defense Grid provides meaningful protection against interaction.

The optimal configuration appears to be 2 copies of Defense Grid, which posted the strongest 59.3% winrate (89-61 record) across 36 entries. Running 3-4 copies shows diminishing returns, with 4 copies actually performing worse at 51.6% winrate, likely due to drawing too many copies or diluting the combo density.

The data indicates Defense Grid serves as effective hate against counterspell-heavy matchups while not significantly impacting the combo's consistency. The 35% adoption rate (78 of 224 total entries) suggests many pilots are already incorporating this technology, with 2 copies being the sweet spot for balancing protection and combo pieces.
