I'll analyze the matchup spread for Grixis Reanimator in Modern over the last 30 days.
Now let me get the matchup data against the top archetypes in the meta:
Grixis Reanimator has a challenging matchup spread in Modern over the last 30 days, with an overall 48.9% winrate. The deck shows polarized results across the format. Against the dominant Boros Energy (12.8% meta share), it splits exactly 50-50. The deck excels against Ramp Eldrazi with a 72.9% winrate (35-13 record) and Domain Zoo at 63.7%, giving it favorable angles against 11.2% of the meta combined. However, it struggles badly against Grinding Breach (14.3% WR, though only 7 matches), and faces unfavorable matchups against Amulet Titan (41.0%), Affinity (44.7%), Orzhov Blink (43.5%), Tron (44.6%), and Dimir Frog (41.4%).
The deck performs reasonably against fair interactive decks like Prowess (52.1%), Jeskai Blink (51.0%), and Goryo Reanimator (52.2%), but loses ground to other combo and big-mana strategies. The extreme weakness to Grinding Breach and negative matchups against multiple 3-4% meta share decks suggests the archetype is positioned as a meta-dependent choice that punishes certain strategies while being vulnerable to the format's combo and fast-mana pillars.
