About DeckDEX - TCG Live Simulator

DeckDEX — Buy Low. Read the Room. Flip It.

You're not a chosen hero. You're not saving any kingdoms. You're a card dealer with a sharp eye and zero shame about reselling a bargain for triple. Welcome to DeckDEX — the trading-card flipping tycoon where the only stat that matters is your bank balance.

It's the stock market, except every share is a dragon. It's a yard sale, except the yard is an entire economy. There's no combat here — just the cold, beautiful thrill of buying a card for $4 and flipping it to some lovely sucker for $40.

💸 So… what do I actually do?

Hunt. Flip. Hoard. Repeat.

  • Spot the underpriced card on a live, shared marketplace full of rival dealers (and a few suspiciously efficient NPCs).
  • Buy it, hold it, relist it higher — and stare at price-history charts like a caffeinated day-trader.
  • Rip packs and pray to the rarity gods for a holo mythic (and not your ninth Rotting Ralph).
  • Complete collections, redeem finished sets for XP, and level your way to a cardboard empire.

🛒 The Marketplace

One board, every dealer. Filter by collection, rarity, finish, condition and price; snipe the lowest ask; or post a buy order and let the deal fill itself while you sleep. Bulk-buy, bulk-list, undercut your rivals — it's capitalism, but with gorgeous art.

🎴 Packs

Open packs with real odds and satisfying reveals, plus the full collector spread: rarities from Common to Mythic, Normal & Holo finishes, conditions from Damaged to Mint, and serial + print numbers for the true scarcity gremlins.

🔥 The Forge

Drowning in duplicates? Perfect. Throw 20 same-rarity cards into the Forge and smash them into one card of the next rarity up. It's recycling — for greed. You hand-pick exactly which dupes to sacrifice, so your best copies stay safe.

🗺️ Adventures

Send a party of your cards on timed expeditions to haul back cash and XP. They might return a little roughed up (a card can drop a condition — but it's never lost). Idle cards are lazy cards. Put them to work.

🏆 Tournaments & Guilds

Field your strongest roster in tournaments. Join or found a guild — chat, pool tributes, grind guild tasks, and climb the leaderboards. Friendship is magic. Market dominance is better.

💼 Build the Business

  • Work & passive income — money that rolls in while you scheme.
  • Staff — hire employees to restock and grade so you can think bigger.
  • Skills — a dealer skill tree: lower fees, more listing slots, burn cards for bonus XP, sharper appraisals and more.
  • Trust & Reputation — ship sales on time, earn ⭐ ratings, climb seller tiers for fatter margins. Flake on a buyer and you eat the refund.

🎡 …and the daily good stuff

Daily quests, login streaks, a spin-the-Wheel for cash, cards and skill points, Albums to show off your collection (with perks), a slick Dashboard that tells you exactly what to do next, light & dark themes, English & Polski, and cloud saves so your empire follows you everywhere.

🚧 Always cooking

DeckDEX is updated constantly — new cards, collections, features and balance tweaks drop on the regular. Got an idea? Vote in in-game polls and send feedback… a worrying amount of it actually ships.
