So TPCi announced that a ban list is coming to Pokemon so which cards will get banned. As of right now expanded is being closely monitored, while they're not really looking at standard. Also keep in mind that the next bans will be at the rotation meaning PRC-BKT (just to stay safe) will likely be looked at.
Trevenant (XY): This card is very annoying to all players, and the fact that it can easily beat darkness (its weakness) shows just how unhealthy this card can be to the format
Battle Compressor: This card helps decks like Night March, since it wouldn't make sense to ban Joltiks, Pumpkaboo, and Lampent, this will basically kill of NM
Archeops (NVI & DEX): This card basically makes a lot of decks impossible to use.
FoGP: Helps T1 Lock which is never fun!
What do you guys think will be banned?
I didn't read that more cards were being banned. I read that cards are being monitored. TBH, I don't think any cards on your list will be banned, but if anything is I think it would likely be Archeops and FoGP. There might be a possibility of Seismitoad or Sableye being banned, but I honestly don't think either will be. The main reason why I think those two cards might go is because they can provide decisive advantages on T1 before an opponent has even had a chance to play the game. That said, I don't think either will go because neither card completely stops the meta. Archeops can be played around with some ease (just not for those FoGP decks lol) because most decks that have evolutions in expanded are running some combination of Hex, Wally, and Evosoda with Archeops in mind specifically and is completely worthless against decks like Volcanion, Turbo Darkrai, Dark Dragons, etc. As for FoGP, T1 Archeops is the most effective counter, but it is far from the only one. There are decks that flat out hard counter the T1 plume that have been around for a long time now (Accelgor Wobb, Primal Groudon, etc.). In addition to this, the FoGP decks really struggle when they miss that T1 stadium.
The reason I don't think Trevenant will be banned is because it *doesn't* easily beat darkness decks. I play against this using Dark Toads pretty regularly and I don't remember losing to it. The weakness absolutely obliterates this deck. Don't get me wrong, the deck can be very frustrating to play against and the T1 lock does the same thing as the two cards above are able to accomplish (create a decided advantage before your opponent gets a turn), but it bricks often enough that it is a risky play. And when it bricks, it is obliterated (in contrast to the decks running FoGP / Archeops which usually have enough alternate options that they can recover from missing the T1 lock)
Battle Compressor is a main component in way too many expanded deck lists for it to go anywhere I think and honestly I don't think the card is all that damaging to the expanded meta.
I don't think the expanded meta is healthy by any stretch, but I also don't know that I think banning these cards is the way to go. There isn't a single deck in the meta where I see it and instantly think "nothing beats that." There are also a ton of deck lists that are competitive (far more than in Standard) with some of them being *very* difficult to beat. For example, if Accelgor / Wobb was easier to assemble, I think a lot more people would play it and a lot more people would complain about it because far fewer decks in expanded use switch cards like Escape Rope / Olympia. There is a lot heavier reliance on Keldeo / Darkrai to retreat out / reset conditions.
Anyway, sorry for the book. I guess to sum up, I don't think anything will be banned right now because I don't think anything is overpowered enough to be considered meta defining. TBH, if anything could be banned, I think FoGP should be banned in the STANDARD format because Deciplume is just that ridiculous. I also think there is a high likelihood that they revisit that new Trashalanche Garbodor card in the next year or so. I think that has the potential to create some real issues.
