>>471086322007-2010 was maximum comp Pokemin for me.
Gen 4 with the ton of new moves, new crossevos, phys special split, and goldilocks zone of total Pokemon count, which meant there was really only NU, UU, OU and Ubers, with all of them being equally fun to engage in with lots of diverse Pokemon and little to no bullshit besides Garchomp, SOULFUL leads and no preview windows, comfy Shoddy/Pokemon Online battles, comfy Pokemon Battle Revolution, comfy everything before Gen 5 pozzed everything with immense power creep and weather spam.
God take me back.
