Going to nominate magnemite for potw 3, even though it doesn't work by nominations. Magnemite hits 14 speed neutrally, so he can go modest and still outspeed diglett/voltorb/elekid holding a scarf. He can also go bulky with eviolite to back up his obscene base 70 defense, which along with his steel typing makes him a hard to break wall. Unlike many other steels, magnemite has plenty of power, hitting 20 spa modestly and running the strongest electric moves in little cup, with STAB tbolt or thunder, along with volt switch. He can also trap steels with hpfire. His excellent defensive typing allowing him to work incredibly with fighting types, with a 4x resist and godly base defence to sponge up brave birds. He has 3 great abilities in sturdy, which can let him switch into a drain punch in a pinch, magnet pull, which can trap steels, and his dream world ability analytic. If you can sacrifice volt switch, magnemite can go incredibly bulky and powerful with eviolite and analytic, giving him an effective life orb boost along with +1 def/specdef.
tl;dr sorry for the wall of text, magnemite for potw3
this world is not real
