SNAKE

Set
Moves: Thunderstrike, Elemental Burst, Tase/Chilly Chomp, Ancient Roar/Chilly Chomp

Item: Ancient Essence

Ability: Awakening/Brute Force

Personality: Very Nimble, Foolish, Tender OR Nimble, Smart, Very Tender.

TPs: 200 Ranged Attack, 200 Speed, 80 Energy, 20 Attack

Reasons
Thunderstrike and Elemental Burst are great STAB options. Tase is useful for utility, and Ancient Roar can be used to escape from opponents that threaten Zuelong. Chilly Chomp is actually a very good coverage move 2HKOs most Florants.

Awakening powers up this Loomian's STAB moves, but Brute Force can be used as long as you don't have Tase.

Ancient Essence maximizes damage on Obsidrugon and Sedimars, crushing them when they're at low HP.
