>>44719119>Landorus-T dominanceLandorus doing basically the same thing for a third gen was getting stale. Its only notable change was Defog and that wasn't enough to make its playstyle interesting after the last 2 gens.
>ClefableLiterally the only thing about Clefable that changed between Gen 7 and Gen 8 was Teleport and Chansey being not as common due to Heavy Duty Boots. People hated the stall teams it was often on with pokemon like Mega Sableye back then and they hate its stall now, too. Clefable was more tolerable when it was clicking Seismic Toss instead of Moonblast.
>CelesteelaThis was shorthand for what Celesteela does(e.g. Leech Seed + Protect being its most common set) as well as throwing Skarmory into the mix like prior gens. More prevalence of the defensive steel/flying playstyle, even if there were differences like Skarm getting Roost.
