The thing is, Shiny Magneton is my fav shiny in all Pokemon, and i recently catched a shiny Magnemite, so im wondering what can i do (i dont like Magnezone shiny)

I was thinking about Eviolite and Gravity, this last one boost accuracy, so Thunder will miss a lot less, i was thinking about Zap Cannon but its around 80% acc for 10 more damage and always paralyze, i think is not worth it.
Gravity also makes flying/levitate/air ballon mons vulnerable to ground, so i was thinking to pair it with a strong Ground type that also has a low accuracy move, like Camerupt, but its too slow and it doesent hit so hard.
I know that Sandy Shocks / Magnezone is probably better but i want Magneton.
Any suggestion?
