Arguably the worst move any bot has played against me:
Conqueror Bot: turn 14
Conqueror Bot plays Necropolis
Conqueror Bot plays Minion
Conqueror Bot discards: Copper, Copper
Conqueror Bot draws Copper, Province, Copper, Minion
BlueSwan discards: Copper, Silver, Minion, Overgrown Estate, Province
BlueSwan draws Copper, Province, Copper, Hovel
Conqueror Bot plays Minion
Conqueror Bot discards: Copper, Province, Copper
Conqueror Bot draws Ambassador, Province, King's Court, Copper
Conqueror Bot plays King's Court
Conqueror Bot plays Ambassador
Conqueror Bot reveals Copper
Conqueror Bot returns Copper to the Supply
BlueSwan gains Copper
Conqueror Bot plays Ambassador
Conqueror Bot reveals Province
BlueSwan gains Province
Conqueror Bot plays Ambassador
Conqueror Bot reveals Province
BlueSwan gains Province
Conqueror Bot draws Gold, Gold, Envoy, Silver, Estate
The bot still had a decent chance of winning before that move:
