Lorcana Ban List Update Detected — What It Means for Co-Movement

2026-04-05


Signal detected: Lorcana ban list update

Our pulse monitor picked up 3 signals from the Lorcana community today, including an updated ban list for Core Constructed. Ban list announcements are one of the strongest discrete events in any TCG — they instantly change which cards are playable, creating sudden demand shifts.

Why ban lists matter for co-movement

When a card gets banned:

- **The banned card** typically drops in price (less demand for competitive play) - **Substitute cards** that fill the same role spike - **The rest of the set** may see correlated movement as players rebuild decks

This is exactly the kind of event that our co-movement measurement (Vibe Score) is designed to detect. A ban list doesn't just move one card — it creates a wave of correlated price changes across the entire set.

Most sets are warming up

You'll notice most sets currently show "Warming up" instead of a Vibe Score. This is intentional — we've upgraded our measurement pipeline to be more honest about data quality.

Previously, some sets displayed inflated scores due to sparse price data. We've tightened the measurement to require consistent price observations before reporting a score. Over the next few days, sets will graduate from "Warming up" to real Vibe Scores as our smart sampling pipeline collects clean data.

**What's actually measured right now:** - 29 sets have enough data for preliminary measurement - 36 sets are in calibration (building their price history) - 6 sets are newly added with no data yet

What to watch

The Lorcana ban list update is our first externally-detected event since the pulse monitor went live. We'll be tracking whether Lorcana sets show a co-movement response in the coming days — that would be a concrete signal that ban list events propagate through the price structure.

For now, the signal is logged. The measurement continues.
