in the silver server please .. somebody help me

You can simply capture 6 geodudes in Mt Moon, train them to level 20 and spam Magnitude nonstop. If the Geodudes have the ability Sturdy, it's literally impossible to lose vs surge, as long as you spam magnitude nonstop. Good luck, buddy!

6. ok I'll try and thank you for replying quickly

I struggled a couple days ago. He wrecked my whole team with his Raichu. However, I trained a sandshrew up to 26 and challenged him again. Once he took out his Raichu, I swapped to a poke with intimidate. Then swapped back and forth two more times to get the intimidate on him. Afterwards, I let my Pokemon die and swapped to Sandshrew and rocked him.

i gonna make its thatkool but with a sandslash i go to train him

Gym lvls are 10* badge number +5 as a rough guide

Also, I use this rule for gyms. I always want my pokemon level to be around (Gym number x10 +5). Surge is gym 3, so 3x10+5 = 35. I'd just level your 30s to 35ish
