I’ll start. Not all are particularly rare and some have come back into vogue with recent patches.

Barb - Town Crier (war cry), punch barb

Paladin - Unkillable Abbot, passive pally

Sorc- ES builds similar to Abbot

Amazon - passivezon, daggerzon, any build that uses a Witchwild String (one of my favorite D2 items)

Assassin - Furysin

General - rares only, naked (aka CE necro)
