Now let me get the matchup data for the top tier 1 decks against Affinity:
Here's how Modern's top-tier decks match up against Affinity over the last 60 days:
The best performers against Affinity are Amulet Titan (63.3% winrate, 31-18 record) and Tron (56.8% winrate, 42-32). Both big-mana strategies can go over the top of Affinity's artifact threats. Boros Energy, the most popular deck at 15.5% of the meta, maintains a favorable 55.6% winrate (89-71) against Affinity, which helps explain its dominance.
Affinity itself sits at 7.2% meta share with a solid 51.2% overall winrate. The matchup is extremely close against Ruby Storm (exactly 50%, 42-42) and actually favored against Jeskai Blink (57.1% from Affinity's perspective, 33-44). Ramp Eldrazi has a slight edge at 53.3% (24-21). These matchup spreads suggest Affinity's position in the meta is reasonable but faces pressure from the top big-mana decks.
