undo to a blank stock, click stock - different cards are displayed

[tswaters]

this only happens after first iteration of the cards.

going back to the checkpoint prior clicking stock will bring back +3 left, and bring back those cards that were drawn into the deck pool.... clicking stock again will pick 3 random cards from the pool again.

changing this involves defining all the cards and their positions when the game starts and eliminating random draws (they are random, just chosen at a different time)
