I really liked to play Battlespot a couple of years ago.
It was fun to win, it wasn't dissapointing to lose, because balance in pokemon was perfect at a time, and winning or loosing a match was a matter of how you play, not wich pokemon you added in your team

But nowadays, every time I go to play in battlespot, I facing against one and the same pokemon over and over again.

Those pokemons were made not for fair play, but for easy wins. They allows player to deal giant damage, gain more than 1 boost in 1 turn, change opponent's pokemon, poison opponent every turn, protect every other turn etc.
Those cards are unfair, and they really ruins all the fun from playing batlespot.

I made a list of those pokemon (see below).
I have some of them in my collection, but I don't use any of those pokemon on my team, because I'm trying to pay maximum respect to my opponents. Howewer, most of my opponents do not respect me, and uses at least one of this pokemon:

Aegislash with substitute and toxic
Celesteela with leech seed
Tapu Lele with Psychium Z
Porygon2 with Eviolite
Tapu Koko with dual screens
Garchomp with choice scarf
Gyarados Mega
Salamence Mega
Lucario Mega
Kangaskhan Mega
Slowbro Mega
Landorus with intimidate
Cresselia with rocky helmet
Heatran with air balloon
Azumarill with belly drum
Toxapex with recover
Tapu Bulu with choice band
Gengar Mega with Perish Song
Serperior with Contrary
Cloyster with King Rock
Mimikyu with Disguise
Glalie with Moody
Mandibuzz with Roost and Foul Play
Kartana with Assault Vest
Xurkitree with Choice Scarf
Kingdra with Drizzle on the same team


Why other pokemon that was ruining the game (rayquaza and mewtwo as example) are banned for play, but those pokemon - are not?
How to counter those pokemons without using some of them?
