Guys, I finished Leafgreen, Heartgold and now I'm in Pokemon Sapphire.
Watt's Magneton is owning my ass. I have:
Mudkip lv: 28
Takedown
Mud Sport
Mud-Slap
Watergun
Plusle lv: 24
Spark
Encore
Quick Attack
Helping Hand
Makuhita Lv: 24
Bulk Up
Focus Energy
Vital Throw
Arm Thrust
Poochyenna lv: 17
Tackle
Howl
Odor Sleuth
Bite
And a zigzagoon that I use only for cut.
Killing Magnemite is easy. Voltorb uses self-destruct whenever I put my Poochyenna to battle. My problem is Magneton. Any suggestions?
