What does everyone think is the most usable card in DP for decks, only pokemon. No trainers and Energies allowed.
Probably one of the most usable cards in the set is Infenape. I also think Empoleon will be used when someone can find a good combo to go with it. I haven't seen the entire set yet but out of the one's I've seen Infernape and Empoleon look the most promising.
Budew's ability to pull out a trainer for no energy is one of the more versitile cards of the set. I think I might have an Empoleon combo, but I have a  lot of playtesting to do.
Azurill's ability to pull any one card from the discard pile for a zero energy attack is not to be overlooked. the drifblim/drifbloom line is going to be teched into all sorts of decks.
elective /even know he to is over rated/
machampe  /hughly under rated/big time
lucario /same a above/
luxray /all around good/
hippowodon /under rated to/
empleon /just good/
dustnoir /just good/
dusknoir's really only extremely useful if your opponent has 1 prize left
hippowdown's sand eject is an amazing attack
machamp is definitely underrated.
i also like cleffa's 0 energy eek attack-draw a card
You're thinking of Crystal Shard. Crystal Shard helps every pokemon out that is resisted a lot. For example, lots of pokes resist Grass nowadays, so a Grass based deck may want to pack one or two of them.
Hmmm....rockets experiment was pretty terrible (needed 2 heads to do computer search, if either of them was tails, you can't play any more trainers) or that tickle machine....or that promo that acted like farmer but ended your turn. :/ Other then that....energy search on your list.
