Ok, time for my likes
:
Electivre: Man, 50 to any of your opponent's Pokemon that so much as breathes with an Energy is pretty nice, as inevitably you will have to start attaching Energy to a backup Pokemon, but this guy makes you think twice about that. LLL for it is a bit icky (meaning you must ordinarily take 3 turns to get it going), but overall it's still pretty dang neat. And if your opponent isn't playing your game, send out Tentacruel LA to help them along, much as how that old Tentacruel/Lanturn deck performed, except Electivire offers a significant upgrade over Lanturn's Split Bomb.
Machamp Prime: Mhmm, still looking pretty sexy. Makes a great addition to any Machamp decks.
Bronzong: Herald of all things Legendary? The only problem is getting him out of the Active position once he uses his attack, but otherwise this guy is infinitely more reliable than Legend Box, though ultimately more time consuming to use.
Yanmega Prime: Is a tad intriguing, but really it's hard to constantly maintain the same number of cards as your opponent has in their hand turn after turn, even if you run 4 each of Judge and Copycat. Seems a little much to be worth it...
Lunatone/Solrock: Heal Block is a nice Poke-Body to aid spread decks for sure, but that's 2 spaces on the bench they eat up, with along with the Uxies and whatnot, can lead to some bench crowding.
Ditto: Semi-intriguing, just a shame its HP is so low and the Poke-Body doesn't stack.
Magmortar: Gives milling decks a new toy with Wildfire, much like the old, old, old Moltres did, but other than that, not terribly playable.
Porygon and Porygon2: Not so much that they're playable, but rather that they mean the PorygonZ Promo and Lv X are still playable. Porygon line is just naturally cool in that regard
Wailord: Even if it's not super playable in Modified, drafting one of these behemoths in Limited would be awesome, 180 HP can buy a lot of time.
All new Legend Pokemon: All of them are playable surprisingly with decks built around them specifically. Kyogre/Groudon and Deoxys/Rayquaza offer the most in terms of raw power, but Dialga/Palkia is infinitely more annoying to deal with, though it can't damage anything on its own directly.
Junk Arm: Definitely useful, definitely worth looking at. Requires a discard of 2 cards, but many decks like manipulating discard effects, and this one gains you a Trainer for your troubles.
Black Belt: +40 damage? I'll waste a Supporter use that turn for that big extra damage It's the equivalent of stacking all 4 Plus Powers you have onto something, and is not insignificant damage when compared with the similar Buck's Training.
Twins: Definitely looking like a staple Supporter, almost everyone at some point in a game is up on prizes (unless you're just completely owning them), so a few of these will give many decks a fighting chance back.
Rescue Energy: Saves you the trouble of having to dig a valuable Pokemon out of the discard, which is pretty nice.
Alpha Lithograph: Azelf LA's eventual replacement for decks needed to know where a valuable prized card is.
So overall, definitely looking like the best set we've got so far in the Legend block...only question is, how much are they going to tear it apart to make our sets so we get them all unequally?
