And Terrain benefits are so important that sometimes just adding a Tapu can defend against another Tapu or general team weakness since you can reset the Terrain to your control.
Magearna is an important mon because it's a role compressor given its Steel + Fairy typing (which is the actual best defensive typing you can ask for) and natural bulk to back it up. AV Magearna can serve as an answer to Tapu Lele, Gengar, Latios, Hoopa-U, Greninja, Alakazam, etc at once, especially given its access to Volt Switch to pivot out slowly into a mon of your choice. Alternatively, Trick Room Magearna and Autotomize Magearna (usually with a Z move) are great sweepers because of Soul-Heart.
Nihilego is another role compressor because it's an offensive switch-in to Mega Charizard Y and Volcarona (usually Scarf Nihilego does this to try and outpace +1 Speed Volcarona's HP Ground) and Fairies, Flying, and Normal abusers that hit on the Special side. Stealth Rock access with a strong HP Ice or HP Fire can make it a significant Sash lead too.
Trick Room can do well this meta because there are a ton of slow mons that perform very well like Alolan Marowak and Magearna, and a lot of reliable Trick Room setters like Magearna itself and namely Mimikyu whose ability lets it set it up without fail most of the time.
Volt Switch + U-Turn are important for positioning and pivoting so that you have the upper hand on the field.
