>>18757908>What got Mega-Gengar and Mega-Lucario banned was that there were only a handful of Pokemon that could counter every single one of their setsMega Gengar doesn't really have counters just because of how Shadow Tag works, not just whatever many sets it has.
Mega Luke didn't just have extremely few counters, it was so fast and had three forms of priority meaning it could easily sweep with a turn of set-up.
Aegislash is one of the best pokemon in the game but it's not because it's an unstoppable threat that can sweep teams after a single free turn.
>>18758053It can do that once at most, because every single one of them does a buttload of damage to it and it has no recovery. It also has no exploitable resistances.
Plus you don't really stop them, you just force them out. Once, because, again, pretty much any strong hit is going to take out a majority of your health.
