The game is played in successive rounds and stops whenever a player accrues 5 or more VP. Each round consists of three steps: First player’s turn, Second player’s turn, and Advance Challenge Track. On a turn, players carry out the following phases in order:

Scoreboard Phase: The active player checks if they meet the conditions of any active Challenge cards. If they do, they gain the appropriate number of VPs, and discard that Challenge.

Activation Phase: Players exhaust Cores to play Action cards from their hand and activate their Champions.

Upkeep Phase: The active player readies each of their Cores, discards their hand and draws a new hand of 5 cards.
