And going last is much too risky for Magneton, as it will die in one blow to many hits anyway - on its evolved form, Magnezone, it is a bad gimmick in OU.
		
		
	 
Considering it's almost a sure kill on both Scizor and Ferrothorn who each are above 20% usage, its a gimmick that probably works more often then some "legit strategies".
I will admit this isn't OU, and Magneton isn't that great here. Pretty much all the Steel types that Magneton want to trap are just as easily beaten by something else. As a default I would say that the niche of magnet pull deserves rank C, but  I'm worried that there would be too much "creep" of ranking. For example, I think Hariyama is decent and I've used him a few times and liked it, but is he really as good or better than Medicham? On the spot I would have to say no.

I'm a bit ify on this idea myself, but I really like the idea of this thread and the potential of its future use.
Would a "soft" limit of ratios be beneficial for each rank?
Something like 1:2:2.5:2.5: (now it's D and no one cares)
for the rank in S:A:B:C:lower
There are currently 8 in S and 24 in A so if we could move 2 more to S and then find 2 that are really not quite A rank, this would already fit to what we have.
I think this might also contribute to discussion because now if you propose a move up or down, you have to propose something to fill it's place. Each rank now has more competition as well.
they can be "soft" limits because if we discuss to change the number of members in S, then the other ranks can increase in size too.
It's just an idea; if this thread is more for just a quick reference and some brief metagame discussion, the ranks probably don't need any caps.
Like I said, I was ify on it myself.
