| Buy $10,000 of packs, sell every card back | About $10,000 back on average (100% expected value × 100% buyback, zero fees) | Can't be worked out: Arena Club doesn't publish pack EV, and its offer nets 90% of each card's estimated value |

Arena Club's standard offer nets 90% of a card's estimated value after its 10% fee; Shiny's zero-fee packs pay 100% with no fee, and $10,000 of packs returns about $10,000 on average. Before you buy, Arena Club shows which cards are in a pack and their hit rates but not what they're worth, and it doesn't publish expected value, so you can't tell whether a pack is priced fairly. Shiny publishes every card's value, the pack's expected value and the odds, and its Full Pack Fairness Replay shows exactly where your roll landed. We found no published way to verify an Arena Club draw.
Competitor details come from their public pages and docs as checked on 2026-10-01. Sell-back figures are averages from each site's published expected value and standard buyback rate; individual results vary, and each site values cards its own way. Live values (prices, odds, EV) change often. If something here is out of date, tell us and we'll fix it.
