Let me pull up the current Modern meta data to analyze this for you!
Now let me get matchup data for the key decks vs affinity's most common opponents, to find what performs well in this adjusted meta. Let me check matchup winrates for the top performers against the non-affinity field.
Interesting! Now let me look at how the top-performing decks (Broodscale, Blue Belcher, Esper Blink) fare against the rest of the field — specifically the other major archetypes.
Broodscale has a tough time vs Ruby Storm and Prowess. Let me now check how Blue Belcher and Esper Blink handle the rest of the field too.
Both Blue Belcher and Broodscale struggle vs Prowess. Let me check Prowess's overall profile and also see how Boros Energy and Ruby Storm handle the adjusted meta (now that Affinity's slice shifts to other decks).
Now let me grab sources to cite.
Here's a thorough breakdown based on the data. Since the MTGO meta is already mostly what we're looking at (69% of the data is MTGO), removing Affinity (~6.5% share) just redistributes those matchup slots to everything else. Here's what that means:
| Archetype | Presence | WR |
|---|---|---|
| Boros Energy | ~19% (inflated) | 52.2% |
| Ruby Storm | ~7.4% | 49.0% |
| Jeskai Blink | ~6.9% | 50.6% |
| Tron | ~5.9% | 50.8% |
| Prowess | ~4.8% | 50.6% |
Blue Belcher absolutely crushes the decks that matter most in an Affinity-free world:
| Matchup | Blue Belcher WR |
|---|---|
| vs Ruby Storm | 81.8% ✅ |
| vs Tron | 64.0% ✅ |
| vs Boros Energy | 53.7% ✅ |
| vs Jeskai Blink | 52.9% ✅ |
| vs Domain Zoo | 50.0% ✅ |
| vs Affinity (gone!) | |
| vs Prowess | 33.3% ⚠️ |
Blue Belcher's biggest liability was Affinity (35% WR) — a matchup that no longer exists in your target meta. Removing it dramatically improves Blue Belcher's expected matchup spread. Its only real remaining weakness is Prowess (~4.8% of the field), which is manageable.
Broodscale also destroys Affinity (89%!) but since that's gone, what's left?
| Matchup | Broodscale WR |
|---|---|
| vs Domain Zoo | 77.8% ✅ |
| vs Jeskai Blink | 63.6% ✅ |
| vs Tron | 61.1% ✅ |
| vs Boros Energy | 50.0% ✅ |
| vs Prowess | 30.8% ⚠️ |
| vs Ruby Storm | 26.7% 🚨 |
Broodscale has brutal weaknesses vs the two most common combo/aggro decks (Ruby Storm + Prowess), which makes it riskier.
Play Blue Belcher. It has the best overall winrate (58.4%), thrashes the #2 deck (Ruby Storm at 82%), goes even with the dominant #1 (Boros Energy), and its worst historical matchup (Affinity) is the one you're cutting from the meta. Prowess is the main threat to watch out for, but at ~5% presence it's not a showstopper.
