Every pack can hold a grail — what changes is how rich the pool is right now. This signal is whether a pack's grail inventory is running above or below its own 7-day average.

Odds = weighted chance per pull. Cards = how many sit in the pool — the draw isn't uniform, so the two don't match.
Pool richness is scored against each pack's own 7-day range. Figures are live from Collector Crypt's published odds and pool. Not financial advice.
