By setting up an elaborate Rube Goldberg-style of card reactions, player Mamytwink and his friends forced 14,745 card draws and inflicted 108,000,000 fatigue damage during a match. It took a little over a day for the game to resolve.
Mamytwink describes himself as “an expert of ‘useless challenges’ in Hearthstone” and said that he will be attempting a “triple world record” soon.
