Problem
TCG pack-opener apps either ran on opaque RNG nobody trusted, or were missing the market half that makes the loop feel like a real economy.
Approach
Five-card mystery packs with provably-fair pull math, six-tier rarity ladder, daily shard rewards, and an instant rarity-floor resale market that bought back duplicates without ever locking inventory.
Outcome
Real loop velocity. Cards moved, daily reward retention held. Regulator shut down the gambling-adjacent loop; engine archived as reference for non-gambling adaptations.
