Magnet Pull, on the other hand, is a constant effect that can be used to trap certain offensive threats or walls on the other team, and since it has STAB Earthquake, it'd definitely make good use of it.
If Magnezone can be successful with it by using Hidden Power Fire/Ground, then Mega Steelix would be excellent with it. Maybe not enough to make it amazing, but many abilities would be better than what it has right now.
