>>42642342There's plenty good pokémon this gen, those in OP's pics get an higher usage rate because they fit in any team they're in instead of requiring you to build a team around them.
>>42643065I know plenty VGCfags with legit teams, they mostly trade among each other, once you get your hands on 6IVs male mons that cover every egg group it's pretty easy and fast to breed whatever you want.
>>42646235Gmax Zard is surprisingly strong actually, the chip damage at the end of each turn is amazing, it lasts long enough and can't be removed by switching.
