Deck Box

Increases the maximum number of cards your deck can contain. The raised cap allows you to include more cards in a single run, enabling broader strategies that would otherwise be forced to cut essential pieces due to slot constraints.

Can be purchased from the village general store, or obtained as a specific event reward in certain dungeon areas.

A utility relic that expands build space, but comes with an important trade-off: a larger deck reduces the consistency of drawing specific cards, which can disrupt combo chains. The relic shines when you genuinely need more slots to fit a multi-component build, but adding cards indiscriminately without a plan often hurts more than it helps.

• Only add cards that don't disrupt your mana cost curve — maintaining ascending cost order is more important than raw card count
• Best suited for multi-archetype builds that need both combo pieces and support cards but can't fit both within the default cap
• Consider adding draw-boosting cards or hand-size Arcanas to compensate for the reduced consistency of a larger deck
• Support cards (healing, buffs, draw) are good candidates for the extra slots, as they add value without requiring specific draw timing
• Think carefully before using every available slot — a focused 20-card deck often outperforms a bloated 30-card deck that struggles to form combos
