Deck Builder uses three expandable slot cards. Each slot starts with Browse catalog, then Or assemble from parts with BX, UX, or CX line chips.
Controls in Deck Builder
Browse catalog opens the picker (Official or Saved segment, search, and line filters). Assemble picks open the part grid with colorway rails when a mold has variants.
Random build (beside slots filled) opens a mode chooser: catalog beys or X parts, with SoftConfirm before overwrite. Per-slot Dices runs the same roulette on one card. Roulette flickers options, then lands with transform sounds when App sounds are on.
Save writes to this device and uniquifies colliding names. After a clean save, New deck (header and rating column) starts a blank draft. Clear deck is for wiping an in-progress edit (hidden once the deck is saved and clean). Mobile shows a Save dock when the deck is dirty. Battle needs two resolvable catalog or Assemble beys.
Deck Rating column
The right column shows tier letter and N/100 from Attack, Defense, and Stamina averages (plus Dash and Burst when bits supply them). Makeup chips and Lineup rows summarize types and weights.
Expand Show battle intel on a slot for CORE STATS and Live Profile. Assemble X from Search or the floating orb sends a complete recipe to the first empty slot.
Saved decks
Saved Decks lists local lineups. View opens read-only detail; Edit returns to Deck Builder; Battle launches Simulator when two beys resolve. View shows a spinner while the deck loads. From Deck Builder, New deck starts another blank draft without retapping the Deck nav tab.
