That makes no sense. M-Ray and Vesipqueen are not turbo decks. Just because a deck gets to its win condition fast, doesn't mean its turbo, its called consistency. You're generalizing WAY too hard here.
You can have consistent turbo decks and consistent decks that aren't turbo. I prefer the term "throw the deck" at the opponent.
I'm not arguing that they occasionally make broken cards, look at LuxChomp for example. But saying a deck is broken, even though its proven to be beaten multiple times, and saying the meta is unhealthy is, quite frankly, bad. You say a "every deck wins" meta sounds good, but its not. Play CFV if you feel that way, you'll see how bad it is. Its skill-less, noncompetitive, and boring. There aren't any "broken" cards in the game right now, everything is balanced. The meta is well rounded, yet diverse. The game is healthy.
LuxChomp wasn't broken, it was consistent. Power Spray was questionable but every SP deck could run it. In a meta where a player can take any deck to a tournament and get results is a good one. It means the only factor (besides drawing well) is the player's skill. I don't play CFV, because I'm only interested in playing decks with birds and if I could build something decent, then I would play but I don't see having a well balanced card game is a bad thing.
Things are bad in Pokemon. They refuse to ban unhealthy cards from the game (something that seems to be changing), they refuse to make counters for decks that have dominated the game and if they do, its FAR too late to be effective (Karen, Field Blower, Oricorio) and game mechanics are broken. Staged Pokemon (unless they are really good Stage 1 Pokemon) are unplayable, the pace of the game is too fast given the kind of game it is, cards are unbalanced and Weakness is broken. There's little to no skill in Pokemon. It's just play solitaire, hope the opponent bricks/ get a matchup where you win because of weakness and act like you're good at the game. There is very little player interaction in this game and little room for counter play. The refusal of simple TCG mechanics like a side board prevents the game from being a deep as it could be and most of the cards in sets are regarded as filler, no matter how good a card is because it's not Darkrai or some other card that shouldn't still exist in the game. If the worst thing I have to worry about is actual diverse meta, then I'm playing the wrong game.
