He basically waste a space, in a metagame where so few Energies are played, and with an not-so-good attack.

I'd just play 2 SW – 2 PL, it adds consistency.

my amphy line is the same,
1-1 claydol
2 uxie
1 Mr.Mime MT/1 Spiritomb PA

i removed manectric completely because while it's body is okay, crobat g's flashbite/gengar's shadow room just get around that, i felt that IF the occasion appeared in competitive play where a pokemon COULD damage a benched, i'd play smarter and outplay it.

my t/s/s great differed,

i personally run 2 bebe's and 2 comm.
4 pokedrawer +
4 pokedex handy
2 super scoop ups(for the uxie re-use)
and 1 prof oaks new theory(hand refresh)
everything else here is the same.

i run 3 DCE and 6 lightning, afraid to cut it down to 5.

this deck suffers against T1 set up decks, in my area i face gengar, kingdra, and my close friend plays a beautifly donk that works amazingly since my pokemon all have resistance.
if the foe doesn't use powers, this deck doesn't work well and has to rely on brute power to beat down other pokemon, and even with 1 lightning and 1 DCE, it's a T2 attack, and decks like i've mentioned are all T1. slowing down these decks is a fantastic way to gain an edge, spiritomb and mr.mime as great for that, if you can't outspeed, then you should slow them down.

however there is no doubt that once this deck is set up, it's very hard to stop it, something constantly happens, the importance of slowing the game down and setting up quicker is essential for this deck to come out on top, and it's perfectly capable of being. it isn't a world's championship winning deck idea but a fun and strong deck regardless and i greatly enjoy playing it.

In the deck I built, I did 4-2-3 Ampharos (2 PL and 1 SW), 2-2 Manectric, 1-1 Claydol, 2-1 Uxie Lv.X (For Machamp and a quick 60-hitter), and I think I may have thrown 2 Unown G in there. Don't quite remember. Then I put in 2 Cyrus' Conspiracy with 4 Poketurns for the Crobat Gs. I said “screw it” to the BTS and just went with the 4 Rare Candies. For the final touch I included 4 DCE, 6 Lightning Energy, and 2 Call Energy.

The deck runs very well and it's a quick set-up. Although it may seem slow and Ampharos being a weak attacker, it really builds up. While the PL Ampharos sends energies around, the SW Ampharos deals 70 as well while hitting each benched for 20. Since SW's attack requires you to discard all Lightning Energy attached to it, you need only to discard one with DCE attached. PL's attack requires you to send any 1 Energy Card attached to any Pokemon in play. Talk about amazing! If you know you're going to die on your opponent's turn, send that DCE down to an awaiting Uxie (to level up and hit for 60) or to another Ampharos.

Another plus to this deck is Flaffy's Tail Code attack. Man did this attack screw me up big time! While focusing on how to keep Ampharos from hitting the field, I neglect the ability of this fluffy evolution. Sending MY DCE to a Claydol, Mesprit, etc. really hurts my game. Considering you can only run 4 DCE, one misplaced is a big hurt.

Sorry to thread-jack, but I just wanted to get it out there that this deck has MAJOR potential and it's sad that all of the cards are more than likely going to be rotated out.
