Reduce your rival's Dream Light to 0. Turns automatically end when no held card can be played with the remaining energy. Start with 5 cards. Each turn: 3 energy and draw 1 card. Hand limit: 7 cards; excess draws are discarded. Deep Freeze costs 3 and also draws 1. Skeleton Key costs 1 and restores 2 energy, capped at 3. Keyboard: 1–7 plays that card; E ends your turn. Shields fade at the start of your own turn unless Lake’s Reflection preserves them. Thorned Promise lasts until your next turn. Attack boosts and piercing last this turn. Pickpocket adds 1 cost until the rival ends their next turn. Each deck has 43 cards (2 of each, except only 1 Deep Freeze) and never reshuffles: once your deck is empty, every draw costs escalating fatigue damage (1, 2, 3…).
