>>32288551Fini is not only too defensive for the Battle Tree, it's also too slow. The thing about Battle Tree is to avoid getting hit in the first place. This is much easier to achive when you're simply OHKOing everything with Specs Psychics at decently high speed yourself. As a side note, Koko cannot be paralyzed, and Confusion isn't nearly as deadly as it used to be.
>>32288556Slow Pokemon are bad in general when it comes to 3v3 battle facilities. They're much, and I mean much more suspectible to stupid Tree RNG shit ranging from critical hits to random flinches to status effects like the one Moltres ended your steak with. This is why BT players fear Pokemon like that meme Scarf Aerodactyl with Rock Slide as it's sole attack - it puts you at considerable risk of getting flinched to death unless you have a 130+ Scarfer yourself (most likely not).
Freeze-Dry is a decent attack but you really should never, ever run Alolan Ninetales without Blizzard as well. If you had Blizzard in that battle, you'd have OHKOed that Decidueye right away and likely 2HKOed the Moltres before finishing it off with Garchomps Dragon Claw (there would be no Gooey to fuck you over). What was your set anyway? Also, why didn't you run Rock Slide on your CB Bulu?
It you insist on using Garchomp in that team you should consider switching Life Orb for a Z-Crystal. All that bulk gained from the Dual Screens and Garchomps nice 108/95/85 defensive stats is just completely wasted when you're losing 16% HP per turn.
