What I really like is the weird way it interacts with Panglacial Wurm, though you need to cast the wurm before you find any cards with a search effect
You may play that card that turn even if Stromkirk Occultist is no longer on the battlefield or no longer under your control
If you have an activated ability that can target it for free , you can mill your entire library
(Look at the top X cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) At the beginning of your end step, surveil X, where X is the number of tapped Assassins you control
So, I will not tell you about generic B/G which, to be fair, doesnt look too much different from mono black
