ลิบองLu Meng

If you play no Attack during your turn, you skip your discard phase entirely and keep every card in your hand.

Lu Meng rewards restraint: if he plays no Attack on his turn, Restraint skips his discard phase entirely and lets him keep every card, stockpiling a hand far past the normal limit. That makes him a patient hoarder who can unload a devastating combo turns later. The cost is tempo — he deals no damage on a held turn, so he relies on others to apply pressure while he builds. He suits a slow-playing Spy or Loyalist.
