This is almost certainly a test-bed for the mechanics of 5e - if this product flies, expect to see the 5e powers available on a deck.
And that's my big concern. I'm okay with 4e, but prefer 3e/pathfinder. If WotC goes in this direction for 5e, it is basically creating a game I will never play.
The randomness of it is fine with me (like the card versions of deck of illusions and deck of many things....both of which I own).
BUT the collectible nature of it...that makes character creation about money spent rather than CREATING A CHARACTER YOU WANT TO ROLEPLAY (never mind the power issues). This takes the utilization of a "character" one more step away from his story and choices he makes/events that happen....and one more step toward being a game piece.
I can see it now:
"Guys, I just got 2 rare powers from my new deck and one ultra rare feat! I'm so powerful now!"
DM: "Ok, let's roleplay how you developed those powers in game."
Player: "Naw, let's roll some dice! I wanna try em out!"
Aberzanzorax: *Is sad.*
