Hi there, welcome back to the game.
I dont know if you were here when Dugtrio's ability Arena Trap got added. It allows you to easy dispatch Chansey/Blissey and many other Pokemons. The same with the choice items. I think that stall is not the same problem like it was before having all these new abilities/items. Check in this same forum and you should see a discussion in which people are talking about banning the mighty Choice Band Crawdaunt, which 2KOS most walls.The same with Choice Band Reckless Staraptor.
You can play mixed sets of Salamence, Garchomp, Dragonite, Lucario, Infernape, etc. You bring Tangrowth, Ferrothorn, Skarmory? Take this Fire Blast from Salamence.
You just have to play smart. Put enough pressure on your opponent, use Hazards (Talonflame loses almost 50% HP at switch on Stealth Rocks). Now they have to either clean that or switch and Roost to recover. If something gets banned cause of no team preview, then the next thing asked to be banned would be Azumarill (which can also be countered by Amoonguss, Tentacruel) or any other Pokemon that means trouble for a team. I dont remember the reasons for Shadow Tag, but it should not be used as example to ban other things.
This is my opinion like a player, like you.
Hi, i wasn't around when that happened i'm gonna have to take my time and give it a good look to all the changes then, thank you for your kind answer :Shy:
