I think the manaphy is kind of pointless. Generally, it just gives your opponent a free KO and can only be used for poorly recycling energies. Sure it lets you search for any card when KOed, but it is still a large price to pay for a single card that could easily be searched through other means... Also, I think silver mirror is additional wasted deck space since it is easily discarded through tool scrapper, a pretty highly run card. It also can only be attached to non-EX. What with this deck's main attackers being EX, it doesn't help much. If you are referring to the plasma blast Kyurem EX, I don't really care for it. Outrage is only useful after taking heavy damage and will be KOed next turn anyway letting your opponent take 2 prizes, which is a pretty hefty sacrifice. Additionally, It's secondary attack is only somewhat better than plasma freeze kyurem's blizzard burn.
Regarding my deck, I do agree on a bunch of those changes. I think 3 Keldeo would be enough, but I'd probably replace it with another BK EX if I can get one. Since Virizion EX/ Genesect is pretty big, BK EX is a good backup to allow you to OHKO anything. Although I can't afford one, if I can trade for one, that would be awesome! Same goes for tropical beach, except that I most likely won't find any for trade.
I do see however where you're coming from with the superior energy retrieval though. I'm thinking I'd prefer 2 super rod over the energy retrieval though, since they can recycle both energy and pokemon, both easily obtained through the many hand renewal cards.
I think heavy ball is cool since it can search for blastoise and BK EX, but I don't have any, so I'll have to trade. I've heard from many that suicune doesn't work well and takes up deck space as any well prepared deck can forcefully switch it with either pokemon catcher or Red Signal (Genesect). They are also easily OHKOed or 2HKOed by most non-EX. So, I'm thinking to replace the suicune with either 2 max potion or 2 super rod and then replacing the Keldeo EX with either BK EX, heavy ball, rare candy, or a max potion or super rod depending on which I use. I think max potion would be useful in combination with scramble switch to avoid discarding, so I'll think about it. Thanks for the input
I think an important part of this deck is being able to cycle energy in the discard too, due to the OHKO tendencies of this format and the BK EX thing... does anyone else agree with me?
