Magic: the Gathering in the UK
Upon proposing a rule change any player may challenge another to a hunting trip.
The proposing player selects an endangered species as defined below. The two hunters both draw and post a picture of a dead animal from that species within 72 hours. The other players then have 24 hours to vote on the best picture. The player with the most votes wins and has most efficiently eradicated their species.
The successful player will earn 15 points as stated in rule 305.
