first of all I have a magnemite set that stalls out the opponent by using toxic and the sturdy ability.
Magnemite @ Oran Berry
Trait: Sturdy
Level: 1
Docile Nature
IVs: 0 HP
- Recycle
- Toxic
- Protect
- Endure
you first use toxic to cause residual damage on the opponent. Then you use protect and recycle intermittently so that you can keep getting your oran berry back as you heal and use it. All the while the toxic poison worsens and your opponent is very pissed.
Endure is just a filler spot in case something weird happens. You'll probably never need or be able to use it. The steel typing helps against sandstorm steams, also oran erry heals it right away. This set is very difficult to get a KO against.
If I'm not clear enough about the oran berry and sturdy, as soon as magnemite is back to full health, which, at its low level it will, its sturdy ability can reactivate. Then if it uses recycle it can get it back. So there you go.
