The collection becomes the deck. 0 cards. No packs. No timers.
BLUDEX BATTLE
Every card in the BluDex, playable. Build a deck of 12, duel the Mirror Deck across the three doors — the Clinic, the Midway, and the BluVerse.
💛 Dark-pattern-free arcade: no timers, no packs to buy, no energy meters. The collection is already yours.
THE DUEL
You and the Mirror Deck each start with 25 NORMAL. Lose it all and the duel ends. Survive 8 rounds and the higher NORMAL wins.
YOUR TURN
Energy equals the round number (up to 6). Select a card, then a lane to play it into. Play as many as your energy allows, then END ROUND. The Mirror answers.
THE STRIKE
After both sides play, each lane compares total POWER. The stronger side strikes: it deals the difference to the other duelist's NORMAL.
KEYWORDS
REGULATE — restore 2 NORMAL when played · STRIKE — +2 power on the round it's played · GLITCH — shuffles an enemy card to another lane · SHIELD — your side of this lane can't be struck this round · ECHO — draw a card.
