Union Arena on Pack Dojo: the facts
- Cards
- 6,803 Union Arena cards across 73 sets, every one dealt with its own card art.
- Rarities
- 11 printed rarities, from Common up to Collab Super Rare.
- Odds
- One card a pull, weighted by rarity: Collab Super Rare is 0.084% of pulls, and the rarest single card is 1 in 11,902. That is Pack Dojo's fair-odds rule, the same in every rarity-weighted universe: the rarest card is about 1 in (cards × 1.75), so a bigger universe has a rarer top card. The full table is under Pull odds on this page.
- Price
- Free. 50 packs a day, shared with every other universe, and up to 250 a day on a year-long daily streak. No ads, nothing to buy and no real money: every pack and every card is virtual, and Pack Dojo is never monetised.
- Binder and trading
- Every pull goes in your binder, which has its own public page. Union Arena cards can be traded and gifted with other members.
Every figure here is counted from the live catalogue and the simulator's own code when the page is served.
How this works
- One card a pull, from 6,803 cards. Rarer cards come up less often — the table above has the numbers.
- One game, every show. Union Arena is Bandai's card game that crosses anime and games, so one pack here can deal a card from any of them. Each show is its own sets in your binder.
- Rarity is printed, and the draw follows it. Common, Uncommon, Rare, Super Rare and Special are the rarities printed on the cards. A starred alternate-art printing is its own card and its own rarity, and so is each promo.
- Promos are their own sets. Every show has a Promos set of event and prize cards — they print NOT FOR SALE on the card, and each one counts separately.
- Shows groups the cards by what they come from — 26 of them, and your binder counts how many of each you have.
- All 6,803 catalogued cards carry art, so all 6,803 are dealt.
- Every English card — 73 sets across every show Bandai has released in English, boosters, starter decks and promos. Cards, numbers, rarities and pictures come from Bandai's own official card list.
- Pulls come out of the same daily allowance as your Pokémon packs. Nothing here touches your Pokémon collection, badges or the Power Pack draw — that separation is enforced in the database query, not by a filter on a page.
