What? that's not great. Run 4 Poketurn.
4 Felicity is needed and Lunatone is the best only ditching one.
I ran registeel but I also ran luxray so that I could put damage on regi with luxray and then heal it off. I didn't really use luxray that much though so I would proably take out the luxray and add in another crobat. You should also play cyclone energy. I don't think you need promocroak and I'd rather play cyclones over teh psychic. I would also play 3 bat 4 turn and then 2 bucks.
Regice is endlessly superior to Registeel.
Players who run Registeel do so because they don't want to make their opponent's Basic switch out (in the instance that that Basic is what they want to be attacking). Why is this an issue though? The Power is, like always, optional, to be used at one's discretion when the situation calls for it. Sableye and Felicity's can make the discard part of both Powers unnecessary with the proper set up, and then Registeel has no use at all except to lower hand count for Cosmic Power or Set Up. Regice, on the other hand, can be amazingly disruptive, acting like a permanent Cyclone energy against SP decks or the odd AMU/Regigigas/Basic-centered deck while also preventing everything else from hiding behind Basic sacrifices like Crobat G/Uxie/Chatot while they try to prepare a response to your onslaught. Having a Power that forces a switch is a great option to have! Note the word "option."
2 Crobat G is fine, but 2 Poketurns is not enough. Go with the full four. I also prefer maxing out on PlusPowers; with 4 of those, 2 Crobat G, and 4 Poketurn, you have ample opportunities to OHKO common Pokemon like Flygon, Luxray GL lv. X, and Beedrill. Promo Toxicroak G isn't necessary if you have enough damage-enhancers to be able to OHKO Luxray GL lv. X.
Now: Registeel, definitely. You don't want to be switching an SP Pokemon to the bench, since SP generally will NEVER have a starter Pokemon. They just go straight into their attacker. Why on earth would you want some bench fodder up there?
This is not always true. You have the endless option of making them switch-- the option. You make it seem like you have to use Regi Move every single turn, no matter what, when you really will only be using it to ditch Magikarp once. From then on out, you have a choice, and you can't tell me there aren't times when switching out your opponent's Basic active is beneficial.
You're making it seem like the only purpose of Regice is to switch, while its biggest contribution to the deck is the double discard without the use of a supporter.
If power locks weren't a problem, I'd play Gyarados with Regice/Steel alone and ditch the Felicity's/Sableye start.
Warp > Cyclone. I don't know why people are playing Cyclone instead. Gyarados almost always has a Crobat G (which ahs free retreat) on the bench so warp is a cylone energy at worst, but also serves as a way of switching (e.g. out of sandtomb lock or if you have a regi trapped active)./QUOTE]
CYCLONE. warp is terrible you never wanna retreat your gyarados anyway. And hey if you're regi or whatever you play gets locked then SSU. Cyclone is tremendously better. Get rid of mr.mime, or night spin dusknoir. massive disruption, you can drag up claydols and things if you time it right.
