Magnetic has found success in Rogue and overshadows Mech Paladins but there's one thing Paladin has that Rogue does not and it's some handbuffs. Now watch this:

Been having a good time with this. The way this deck wins is simple. You handbuff Magnetic Mechs and deal damage to the enemy hero. This deck also runs Amitus which, with a single +1/+1 buff, becomes an absolute menace. You can attach stuff to Goldwing to delete chunks of the enemy hero's Health.
It needs a board to be good but Replicating Menace and Annoy-o are great here.
There are 4 Legendaries in this deck, although 1 is free and 1 is from a mini-set.
This deck doesn't run Inventor's Aura despite being 90% Mechs.
It's probably not that good but it's fun :)
