[@Tangletail] Perfects stats or no, Sneasel is kind of a wet paper towel defensively. Against a steel type attack, assuming it's close to the same level, it's almost guaranteed to lose.

I did a mock battle on Showdown to test how a battle like that might go. Stick eviolites on both of them and see if he falls, though I doubt it'll take one attack. Even if he does, this isn't the game. Sneasel is much faster than Magnemite so it wouldn't be unrealistic to have him dodge an attack or two while getting some attacks in :P
