RE: Miasma Wind (Leafeon, Espeon Prime, Blaziken & Roserade) All help needed Before States!!
Here I am again xD
Emm... yep, I want to take my deck to states or something... I feel a lot of potential in Leaferade (also, no one uses it).
I played against DialgaChomp twice, and I won. It's not very difficult because Dialga only cuts the HP boost, but you still can do 150 (also, I don't run any HP boost, so Dialga G Lv. X doesn't affect me =P). If Garchomp is active, use Leafeon or Espeon Prime. If Dialga G is active, use Leafeon or Blaziken (I recommend Leafeon). You always have the last resort: Roserade with its 20 twice each energy attached to it. And also remember: if the HP boost is blocked, you always have Espeon Prime. Against those decks (or a Charizard deck) it's better to build 1 Leafeon and 1 Espeon Prime as main attackers, instead of 2 Leafeons.
Against LuxChomp... erm, I played once, and the opponent's deck was horribly builded, so he could never build anything. But it's a deck that it's a challenge against any deck (well... not a challenge if you have Donphan Prime or Machamp...). It's like Jumpluff (oh, how I hate that deck...).
Your decklist looks like mine, adding Uxie, Azelf Espeon and Umbreon MD. It's a nice decklist, maybe you'll have some problems building the entire thing (I mean, Umbreon/Espeon MD, Blaziken, Roserade, a pair of Leafeons and a lot of energies to use on Roserade... also 1 or 2 Unown RETURN). I dunno if you're already doing it, but I recommend you building in this order: Leafeon, Roserade, Blaziken, another Leafeon (or Espeon Prime), Umbreon/Espeon MD. IMO, Interviewer's Questions is a very useful supporter in this deck, because you can have a lot of energies in your deck for Roserade. I know that everyone says that is highly recommended use Espeon and Umbreon MD for this deck, but for me it's like mixing an Eeveelutions deck with a Leaferade deck xD
If I have some idea to help you, I'll post it later (Y)
P.S.: Oh, I'll post a strategy-help of this kind of deck against other famous decks.
