Well, since it’s in game, Sticky Web usually isn’t a great option. If you can train EVs via SOS chain or whatever, then that would be great, though it doesn’t really matter. I would use Galvantula and get rid of Vikavolt, for the simple reason that they share a typing and Galvantula is fast. Really, speed and power are usually preferred over more power and bulk but bad speed. Here’s the set I would use for in game (note that I’ll put EVs, but they are completely unnecessary):
Galvantula @ Electrium Z
Ability: Compound Eyes
EVs: 4 HP / 252 SpA / 252 Spe
IVs: 0 Atk
- Bug Buzz
- Energy Ball
- Hidden Power [Fighting] / Hidden Power [Ice]
I recommend checking in with the Hidden Power person in the daycare before teaching it Hidden Power. If you can’t get HP Ice/Fighting, I suggest Volt Switch in Hidden Power’s place. Electrium Z turns Thunder into a 185 BP move. The EVs, again, are unnecessary. Bug Buzz you already have. Energy Ball is a TM in Lush Jungle. Thunder can be purchased for 30,000 Pokedollars at the Seafolk Village Pokemart (if you’re not that far into the game yet, Thunderbolt is a TM in Sandy Cave, which you can use until Thunder is obtainable). Hidden Power is a TM that you obtain from the Nursery, where you can also check HP type. Volt Switch is from Mount Hokulani.
So, in conclusion, I would train up Galvantula and get rid of Vikavolt.
Hope this helps! :)
PS: the tags are confusing me.... in game and competitive? So I thats also why I did a competitively viable set....
