For magnemite, you could pick up machop, makuhita (or even a shroomish) for a fighting type. Granted, evolving shroomish that early is a waste.
>>48893527>Treecko doesnt get a physical attack stab until level 29.In the original games, the treeko line has no physical attack stab, despite being able to learn screech. The only upside in the Wattson fight is he'll only use sonicboom against grovyle, so you know exactly how many hits you can take.
