Wheels
Make everyone discard their hand and draw a new one, then punish them for it.
A wheel refills your hand and everybody else’s at the same time, which sounds like charity. The trick is the cards that turn other people drawing and discarding into damage or creatures for you. Without those payoffs a wheel really is charity, so build the payoffs first and the wheels second.
Not this one?
Leave empty for no limit. Cards you own do not count.
