I'll analyze the performance of Eldrazi Ramp with and without Magus of the Moon in recent Modern tournaments.
Based on the last 60 days of Modern tournament data, Eldrazi Ramp decks playing Magus of the Moon show a notable performance advantage over those without it. Decks with Magus of the Moon posted a 56.4% winrate (31-24, 3 draws) across 14 tournament entries, while decks without Magus achieved only 49.6% (283-287, 38 draws) across 127 entries. That's a 6.8 percentage point improvement in winrate.
However, adoption remains quite low at just 9.9% (14 of 141 total Eldrazi Ramp entries). This suggests that while Magus appears effective in the current meta—likely punishing greedy mana bases in decks like Domain Zoo and four-color piles—most pilots aren't running it yet. The smaller sample size means these results should be interpreted cautiously, but the trend is clear.
The data indicates Magus of the Moon could be an underutilized tech choice in Eldrazi Ramp right now, potentially offering an edge against the prevalent multicolor strategies in Modern's current landscape.
