>>34366497Tangrowth faces a lot of competition as a defensive Grass-type from AV Tapu Bulu, who has a much better typing and more offensive presence.
Zapdos struggles to fit on teams in a metagame where CB T-tar is extremely common, as well as Pokemon such as Heatran and even Mega Tyranitar.
Weavile is dropping due to Naganadel leaving the tier, which is the main reason why it rose in the first place.
Mega Latias' only real viable set now is its CM Stored Power set, but vs T-tar teams, it still struggles quite a bit.
Garchomp is practically not worth using in this tier anymore. It's so outclassed on so many levels as a breaker, revenge killer, and offensive rocker, and is probably going to keep dropping.
Tapu Fini has always faced a lot of competition as a Defogger, but with USUM bringing more options, Tapu Fini is becoming less and less viable.
Why would you actually use Zard-Y in this meta? Honest question though.
Mega Gallade is dropping back into obscurity, especially considering its main niche at breaking Mew balance, is no longer even applicable considering Mew is falling off quite a bit.
Much like Growth, Amoonguss faces a lot of competition as a bulky Grass-type, from Bulu, Growth itself, and Mega Venusaur, and Pex to an extent (yes ik not a Grass).
Mega Gard has an extremely small niche over Lele because of its slightly higher Speed stat, but we felt like that's just not enough to keep it ranked, especially when taking the mega slot into account
