Th 6 and below champions?

Im wondering if there are any th 2/3/4/5/6 champs left except for Killer and Pelicantacos. (both th 6)

i found sometimes TH7 , but never saw a TH6 or below

All other th<6 are getting drained by people 2000 cups below, so unless there's some other TH6 champ, they're probably the only ones
