โลซกLu Su

At your draw phase you may draw two extra cards. If you do, you then give half your hand (rounded down, counted after the ordinary draw) to whichever other player holds the fewest cards. Declining simply draws normally.

Once per play phase: name two other players, discard cards equal to the difference between their hand sizes, then swap those two hands entirely. If you cannot pay the difference you cannot use it.

Lu Su plays the table, not his hand. Open Hand nets him two cards every draw phase and hands half his hand to whoever is poorest — which sounds like charity until you notice the poorest seat is usually the ally who most needs reviving, and that he chooses whether to fire it at all. Alliance is the bigger lever: pay the difference between two players' hand sizes and swap those hands outright, which can strip a loaded Rebel and arm a starving Loyalist in one action, or hand a Spy a hand they cannot use. It costs him real cards, so it wants a full hand first — which is exactly what Open Hand builds. His weakness is 3 health and no defensive skill at all: he shapes the game but cannot survive being the target of it.
