KEY TAKEAWAYS
Blue Belcher's biggest problem matchups are Esper Blink (26.3% over 19 matches -- a large enough sample to treat as reliable) and Prowess (38.9% over 36 matches). Esper Blink's disruption and blink-based interaction appear to be a consistent wall. On the positive side, the deck crushes Ruby Storm (80%) and Fight Rigging Eldrazi (75%), and goes even or positive against the format's #1 deck Broodscale (50.0% over 52 decisive matches). Note that matchups against Devoted Combo, Boros Energy, Neobrand, and Boros Ponza all have sample sizes under 15, so treat those figures with some caution.
