Crown Prince
Night - Duration - Reaction
$5
Set aside an Action card from your hand (on this). At the start of your next turn, play that card twice.
-
When you gain an Action card, you may discard this to set that card aside, playing it at the start of your next turn.
The on-play effect is essentially a delayed throne room, played at Night, and thus non-terminal. Useful if you run out of Actions, or if you have an Action card that wouldn't do much good this turn. The reaction is a weaker form for a gained Action card. Most commonly it would be used with cards you buy, or that you gain in other ways during your turn, but the reaction can also apply if you gain an Action card on someone else's turn, such as your opponent buying Bargain, or gaining an Action card from your opponent's play of Swindler
I went through several different versions, using different reactions, until I settled on this one. One version was "When you gain an Action card other than during your Action phase, you may reveal this to put that card into your hand.", which would allow you to use the on-play effect right away if gained during your Buy or Night phase, and would've comboed really nicely with Villa or Cavalry's ability to return you to your Action phase, letting you play newly-bought Action cards right away. But, that seemed way too strong. I also tried out "When you gain an Action card on your turn, you may discard this to play that card immediately.", but it felt inconsistent to have the reaction let you play the card immediately, while the on-play effect was delayed till the next turn, and also doesn't work as well for Actions gained outside of your Action phase, especially Night-gained cards
Sleigh would make a nice combo with this. Use Sleigh's reaction to put a card you bought into your hand, then Crown Prince it. Especially nice with expensive Action cards like King's Court or Hunting Grounds
I'm really not sure of the price. The above-the-line part by itself would probably be fair at $3. Throne Room is $4, and this is delayed, so by the same logic of Mastermind being cheaper than King's Court, it should probably be cheaper. The reaction makes it stronger though, since you get to play a new Action card on the very next turn. Topdecking cards already allow you to do that, but this allows you to do it non-terminally and without taking up a slot in the hand - similar to topdecking + playing Ghost Town. Is $4 enough, or should it be bumped up to $5?
EDIT: Changed to $5, the reaction makes it too strong, I think, to cost $4
