I think I'm going to change Hounds to the 4-cost version. (Trashing option, +1 coin instead of Buy, +1 Card instead of 2.)
To get rid of some of the excess trashing among my cards, I'm going to change Accomplice.
A village that also trashes? So powerful. Instead I'll change it to discard. Feels slightly weak at 5, but too strong for 4. I'll think on it.
Edit: Ooh, I just got a good idea. "If it's an Accomplice or an Attack card, put it into your hand. Otherwise you may discard it."
I need to change this to "At any time during your turns" instead of "At the start of each of your turns." Otherwise it's a bit weak. This will also allow you to do interesting things during discard attacks. Especially Pillage.
Edit: Never mind. I like the 3-cost Hounds and Accomplice the way it is. I will reword Cell, though.
