+Prince has you play the same cheap action every turn for the rest of the game. The turn you play Prince, you set it aside with an Action from your hand costing 4 coins or less; then every turn after that you play the Action at the start of the turn, and then set it aside again when you discard it from play. If you don't discard the Action then you stop playing it with Prince; Prince at that point is just set aside doing nothing for the rest of the game. That won't normally happen but will happen for example if the Action is a Feast or Mining Village and you trashed it, or if it's a Duration card and so it stayed in play, or if it's a Madman and was returned to its pile, or if it's an Island and was set aside, or if it's a card you put back on your deck with Scheme. The set aside Action technically goes back and forth from being in play to being set aside each turn, but in practice it's easier to leave it sitting on the Prince and just announce resolving it each turn.
