Here's the rule: You win if you eliminate the player on your left. (If some other player causes their elimination, the game continues without that player and your goal changes to the new person on your left.) It's basically a standard Attack-Left Defend-Right structure, used in Grand Melee Magic (which inspired Giant Circular Fluxx, the pondering of which got me to this new idea.)
