I haven't really been following b2w2 updates for fear of spoilers, but there are no stat changes in the new form? Not even an ability change? That's kinda shoddy. The new form looks cooler, but all it really does is give away one of the moves in your set
Also, for anyone who already had used Keldeo, as many have despite it not being available through ah... the usual methods, his new (tutor) moves are:
Aqua tail, bounce, covet, endeavour, helping hand, icy wind, last resort, sleep talk, snore, superpower
A couple of interesting changes, though not many of them are really very useful. Aqua tail and superpower are nice moves, but Keldeo is special-focused.
Rest sets are now an option due to snore, sleep talk and rest being in Keldeo's movepool, if you want to surprise people, I guess...
Wow, looking at his movepool, he doesn't have any options for special attacks, even with the new additions :s
