RE: PokeBeach Official Tier List
I'd say it's more like
Tier 1:
ZekEel
Darkrai
Tier 1.5:
CTM
Mono Fighting
Tier 2:
Klinklang
Empoleon
Vileplume variants (not just Accelgor)
Quad Entei
all the other stuff you said I guess
I think that there's no dispute that Darkrai is the card that's defining the format right now. It's fast, consistent, has a great ability, great attack, can deny KOs, has synergy with quite a few cards, and can take multiple prizes in the same turn, even against non-EX cards. ZekEel stands up to all of that very well thanks to Terrakion, and has a pretty favorable matchup there. However, it's a cut below Darkrai when playing the other decks in the format simply because it's one of the slowest decks nowadays.
Mono Fighting is the lame meta-counter deck with good enough matchups to keep it winning but really isn't that amazing when it comes down to it. CTM is a very good deck, but it just falls into the shadow of Darkrai and Eelektrik when you look at what it takes in this format to be successful. It's too vulnerable to N, doesn't offer very consistent energy acceleration, can't use Smeargle very effectively thanks to Celebi, struggles to consistently set up Retaliates, almost all of its main attackers have nasty weaknesses, it lacks late-game power, and just doesn't have the stellar matchups that Darkrai and Eelektrik have. Every matchup with CTM is about 50-50, so every matchup you play is going to be a struggle. However, all four of these decks are still the best available. There's just a clear division between the top two and the bottom two.
All of the Stage 2 decks and other random decks (mostly Quads) simply aren't as effective as the "Big 4" decks at trying to do what they do, but at the same time are able to bring enough unique benefits to the table to be playable. Whether it's draw, board control, disruption, or some combination of these things, they have some unique niches for lack of a better word. When it comes down to it, though, they lack the speed, consistency, and/or matchups that keep the big four decks on top. Darkrai and CTM are very good at exploiting early-game weakness, while Eelektrik is very good at exploiting late-game inconsistency and Stage 2 decks tend to have both of those things. And the Quad decks have too one-dimensional of a strategy to be popular or great plays.
The nice thing about this format, though, is that there are quite a few decks with the potential to be Tier 2 and playable, even outside of the ones already listed. Magnezone, Lugia Legend, Typhlosion, Emboar, various Plume variants, etc. are all decent. I think the real debate in this thread is going to be about which decks to include in Tier 2 and which to leave out of it, not which decks should be in Tier 1 and 1.5.
So, thoughts, on reorganizing it to be like what I put?
