But you can just give Hound +2 actions right?
The original challenge was to find a version of Demonic Tutor (a non-terminal card that digs for the card of your choice and puts it in your hand) that works for a low price, i.e., $3 or $2. According to Donald's words somewhere, DT is a concept that can't work at any reasonable price in Dominion. The official card that approaches the concept the most is scavenger, which is terminal and leaves the card on top of your deck.
I thought of the requirement to have a copy of the card in hand as a nerf to the concept. Axxle insightfully pointed out that this now looks like a throne room variant. That doesn't mean this card wants to be a throne room variant though, it just means that it is not a very strong card, and well, I am trying to find a cheap card here.
Also, as LastFootNote mentioned, digging causes a lot of downtime, so a village that digs might not be very cool in Real Life games...
Anyway, the idea is to make it so you can't dig for any card, or else it can fail, or else there are conditions... Ideally, I would like a card that can dig for different cards each turn. Hmmm... I just had a different, crazy idea.

Name a card. The player to your right reveals a copy of that card from his hand (or reveals a hand with no copy of the card). If she did, reveal cards from the top of your deck until you reveal a copy of that card; put it in your hand and discard the rest.
Hmmm, lots of problems with it, but it might be a start...
