Stone Brain vs Chalice in Tron Sideboard

Great data! Now I have a clear breakdown. Let me put this together clearly for you.

🧱 Tron Sideboard: Stone Brain vs. Chalice of the Void

Last 60 days | 425 Modern Tron entries

Match Winrates by Sideboard Configuration

What this tells us:

📌 Stone Brain (71.8% sideboard presence) is the most popular of the two by a wide margin — nearly 3/4 of Tron pilots run it. Performance-wise, it nets ~48% winrate whether paired with Chalice or not, which is basically neutral.

📌 Chalice of the Void (46.4% sideboard presence) shows up in almost half of Tron lists, but decks running only Chalice (no Stone Brain) actually clock in at the worst winrate of the four groups at 44.3%.

📌 Running neither produces the highest winrate at 49.1% — though this is a small sample (62 entries) and likely reflects pilots who opted for other tech, not that cutting both is strictly better.

Bottom Line:

The data doesn't show Stone Brain or Chalice being a clear winrate driver in isolation — Tron sits around 47–49% regardless of which you run. Stone Brain's near-universal adoption likely reflects its role as narrow but necessary insurance (e.g., naming combo pieces in Living End, Cascade, or Amulet) rather than a raw performance booster. Chalice being worse in isolation is a bit surprising and may reflect meta-targeting mismatch rather than the card being bad.
