You can find one on Cinnabar Island.
u need to treade it with a magmarizer
You dont
You must trade Magmar while holding the Magmarizer
After you beat all 16 gyms and get Rock Climb go back to cinnebar and climb up on the rubble. The magmarizer is up there.
Magmar in the Safari Zone then trade it while holding the magmarizer.
Trade holding magmarizer
You cant, You can only get The "Magmarizer"Unfortunately, the only way to find an electrizer in Soul Silver is if you use the Pokewalker. I don't know the route or the number of steps to get it, but if you go on seribii.net then you can find out.
in Pokemon soul silver you will find it (it is not in the grass)
You find Moltres in Mt. Silver.
You can not. There is no possible way of getting a Deoxy's in Pokemon Soul Silver.
