Basically every Pokemon that evolves when traded holding an item, now just has to level up holding that item.
Haunter evolves when leveling up holding a Spell Tag, Machoke a Black Belt, Kadabra a Twisted Spoon, and Graveler a Hard Stone (Alolan Graveler instead evolves at magnetic areas).
Boldore evolves holding any evolutionary stone, while Conkeldurr evolves holding a Macho Brace.
Karrablast and Shelmet can only evolve if they defeat the other in battle.
