When Noble Benefactor dies, each player may search their library for a card and put that card into their hand. Then each player who searched their library this way shuffles.
The player whose turn it is searches their library (or chooses not to), then each other player in turn order does the same. Then the player whose turn it is shuffles their library (if that player searched), then each other player in turn order does the same.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
