Opposing Steel-type Pokemon cannot switch out while the wielder is on the field. A Steel-type Pokemon can escape by using Baton Pass, U-turn, or Volt Switch (as long as the wielder isn't immune to Volt Switch), or by holding the item Shed Shell. Magnet Pull does not prevent the effect of Eject Button.
When the wielder is first in the party, the chance of wild encounters with Steel-type Pokemon occurring is increased.
A great ability, simply for the fact that Steel-types are so common, and so dangerous, in OU. Magnezone can trap Ferrrothorn and Scizor, and then either set up on it or KO it to allow another Pokemon to sweep. Magneton can do the same job viably too due to its higher Speed, and is available in the lower tiers. Probopass, however, is fairly terrible and can't do anything besides keeping the Steel-type on the field.
