What Pokémon can learn the most partial trapping moves? example fire spin, bind, wrap
Smeargle. But if you don't want that, Onix and Steelix at 3 trapping moves.
Onix and Steelix can learn Bind, Sand Tomb and Block.
EDIT: Huntail and Gorebyss can learn Bind, Whirlpool, Clamp and Infestation. Thanks SM.
Hope I helped!
