I am searching for decks which containst as many different cards as possible that are from commander/planechase/conspiracy sets which were never legal in standard (and therefore in modern too). Cards like Scavenging ooze which were later reprinted in standard legal sets of course do not count. These cards make me interested in legacy so the format is not just modern with less banned cards and painless duals. Not sure if include portal too. If reprinted in masters sets is still fine.

So far there are two established decks I can think of

Death and Taxes:
Recruiter of the Guard
Brightling
Sanctum Prelate
Palace Jailer
Containment Priest*
Council's Judgment*
and some more experimental cards
Hallowed Spiritkeeper
Alms Collector
Selfless Squire
Nahiri, the Lithomancer

BUG Fit:
Baleful Strix
Toxic Deluge*
Leovold, Emissary of Trest
Meren of Clan Nel Toth
Titania, Protector of Argoth
Flusterstorm*
and some more experimental cards
Edric, Spymaster of Trest
Centaur Vinecrasher
Damia, Sage of Stone

* mostly sideboard tech

I may have left some out, but still, is any other deck that can play more exclusives than these two or various brews around these?
