[6] For a 360-card cube, heres a good distribution: 250 cards, with 50 for each color 50 red, 50 green, 50 black, 50 white, 50 blue 50 multicolored cards 5 each for the 10 color pairs 30 artifacts If you include a mono-brown archetype, consider doubling this number (at least) and trimming on the individual colors, since anyone can draft colorless cards
But as the turns pass, players will see their room for maneuver expanded, being able to burn more metals without having to lock them or activating passive effects associated with a metal related to their character, which means a slight point of asymmetry
This new expansion to the TCG came with a full card redesign
