I'll need to gather several pieces of information simultaneously — let me look up the archetype, search for the relevant cards, and get the Modern format details all at once.
Got all the IDs. Now let me query the database to find mirror matches where we can identify the specific card configurations you described. This is a complex query — I'll look at mirror matches within the last 12 weeks and filter entries by those exact card counts.
Zero results. Let me check if the card counts are being captured correctly — the deck_cards board filter may be needed, and let me also verify what talisman/gemstone/forest counts actually exist in Broodscale entries to make sure the profiles are realistic.
This tells me a lot. Gemstone Mine doesn't appear in any Broodscale mainboard entries in the last 12 weeks — every single combination shows gemstone = 0. The profiles you described (with 1 Gemstone Mine) simply don't exist in the data. However, I can see the closest real-world analogues to your profiles do exist:
Let me run the mirror matchup on these realistic profiles instead:
Here's what I found — and an important caveat up front:
Gemstone Mine does not appear in any Broodscale mainboard in the last 12 weeks — gemstone = 0 across all 1,133 entries. Your exact profiles couldn't be matched. I instead ran the closest real equivalents:
| Matchup | Wins | Losses | Winrate |
|---|---|---|---|
| Profile A (2 Talisman, 5 Forest) vs Profile B | 10 | 6 | 62.5% |
| Profile B (0 Talisman, 6 Forest) vs Profile A | 6 | 10 | 37.5% |
Profile A (with Talisman of Resilience) wins this pseudo-mirror, going 10-6 (62.5% WR) against the no-Talisman build across 16 total matches in the last 12 weeks.
⚠️ Small sample size warning: 16 matches is a limited dataset. Treat this as a directional signal, not a definitive conclusion.
📊 Sources — Data from Modern tournaments (last 12 weeks, 2026-06-30 to 2026-09-22). Gemstone Mine absence confirmed across all 1,133 Broodscale entries in this window. If you're seeing Gemstone Mine in a specific list, it may be a sideboard inclusion rather than mainboard.
