"JM: This might give some balance issues considering how easy it is to get 2 of the same common (think Hungry dead issues, only less op). The suggestions are funny though. This is something to keep in mind."
Even if you had multiple of these cards, you could play each one only once per turn (cards are still listed as 'New' until the end of your opponents next turn). Besides, if you have a bunch of these cards in your hand, you seriously limit your options in terms of card play.
The only issue I could see would be that you could burn through a bunch of turns and get a time elapsed victory more quickly than you should normally be able to.
