Deck combat begins with four random cards, replenishes used slots every ten seconds, and permits one discard that refreshes every thirty seconds.
The squad leader draws four random cards the instant deck combat starts and may play any or all immediately, including summoning four totems at once if all four appear.
Each played card is replaced by the next card in deck order after ten seconds. A card may instead be discarded, moving it into an unusable discard pile for the rest of that combat.
Only one discard is initially available, and that capability refreshes every thirty seconds. Once the leader has played or discarded every card, normal spellcasting and inventory access return.
Four floating cards above a timed draw track, with a discard slot slowly recharging.
The hand cycle controls tactical tempo, exposure, and how quickly a leader can escape the deck lockout.
