Cards are your primary arsenal in Lost In Random. Once you've obtained a Card Binder from Mannie Dex, Even can wield up to 15 cards at once, which come in five varieties: weapon, damage, defence, hazard, and cheat. You can buy cards from Mannie directly with coins, but some are earned after finishing a fight.
Initially, that card binder will automatically fill up but once you've earned more than 15 cards, organising them can seem a little daunting. Thankfully, sorting out deck isn't too hard, and here's what you need to know.
Lost In Random: How Do I Organise My Card Deck?
First, head to the inventory screen, where you'll find what cards Even has obtained. Scrolling between card pages with L2 and R2 (using a DualSense controller as reference for this guide), press X to add a card into your deck.
However, if you've got more than 15 selected, Lost In Random won't accept it, so you'll need to remove some. To do that, go to the left-hand side of the inventory screen, which lets you scroll through previously selected cards. Simply press X to remove them, and adjust accordingly.
