Maybe someone as mentioned this but what about Magneton and Nuzleaf?Another interesting thing is the Steel types: only Metang and Lairon are allowed. Lairon has the rather threatening Head Smash off 90 base attack and 60/140/50 defenses. Metang has the more balanced 60/100/80 defenses, but has only a 75 base attack Meteor Mash to threaten opponents.
Also, no Dark types in the tier at all. Great for Kadabra and Haunter.
