Well, I KO'd my self by decking out...for the seventh time in a turn (I think, the damage that last one should have been 70)
Turns out running a Blue/Purple deck with lots of draw cards allows for infinite turns (if not for the deck out damage), I could have won but choose to keep drawing cards (I had a deck size between 50-60 cards)
The returning discard to the deck when out of cards is very strong (there is also a 3 Green card that just moves anything there to the deck...using it twice or after decking also deals damage I found out) and how it is handle later on may want to be changed
On the other side of things, enemies current don't seem to work on "deck" logic and just draw cards they can always use...I don't know but it feels kind of like they are cheating as the never get 'duds' they can't use, I don't know maybe if they had bigger hands the chance of them getting 'duds' means they may have more or less options per turn
