I plan to use power cards a bit differently.
The DM takes care of the cards in between games (I will probably store them in a few of my old MTG card boxes...) and hands them out at the beginning of a session, apart from already used dailys. As an encounter or daily power is used, the card goes to the DM, to be handed back after a short or long rest.
This way we minimize confusion on what powers can be used or not. The accessories needed will be three card boxes (unused player/item cards, used player/item cards and DM cards) and one sleeve plus old MTG land/common per card, all of which I have already.
