I'll analyze Mystic Forge combo's performance against the top Legacy archetypes over the last 3 months.
Now I'll check Mystic Forge combo's matchup performance against each of the top 5 other archetypes:
Mystic Forge combo shows mixed results against the top Legacy archetypes over the last 3 months. The deck performs exceptionally well against Mono Red Prison with a 75.0% winrate (36-12 record), and favorably against Izzet Delver at 60.0% (21-14). However, it struggles against the format's most popular deck, Dimir Reanimator, with only a 45.5% winrate (71-85 record). The matchups against Show and Tell (51.6%) and Dimir Tempo (46.3%) are roughly even to slightly unfavorable.
Mystic Forge combo represents 5.0% of the Legacy meta and maintains an overall 51.8% winrate. Its polarized matchup spread suggests it's well-positioned against prison strategies but vulnerable to graveyard-based combo decks like Reanimator, which dominates 17.9% of the format.
