I was playing Heart of Crown in person the other day and we had this situation come up 3 times, and never found any distinct ruling. Hopefully someone can tell me how the videogame version treats it.

So Cait Sith lets you draw 1 and look at the bottom of your draw pile, then choose to discard that card or put it at the top of your draw pile.

I draw a card, and it empties my draw pile. Does the "look at the bottom of your draw pile" now fail, or does it force a reshuffle before doing the ability?
