Build from every card in the Welcome to Night City set. The builder enforces the real deckbuilding rules as you click: 40–50 main-deck cards, exactly three unique Legends, copy limits, and each color's RAM ceiling set by your Legends — with an AVAILABLE RAM readout, a RAM filter, and a fits-my-Legends toggle. Import a deck from CHOOMDEX or export your build to play it online.
