Stuff I'm trying to get for this deck:

Conspiracy
Cabal Coffers (have)
Urborg, Tomb of Yawgmoth
Cairn Wanderer
Swords to Plowshares
Path to Exile (have, but am currently using.)
Filth

OK, as you can see, the idea is creatures. Rebels for the reasons stated above, Clerics for Scion of Darkness, Changelings for being both rebels and clerics (and Changeling Hero in particular having nice Champion shenanigans,) and just general Good Stuff beyond that.

I've got a couple questions, though:
-Is the cleric package too schticky? Absent Scion of Darkness, most of them are at best off-tribal utility creatures (Order of Whiteclay is a good reanimator, by absent Scepter of Dominance or Icy Manipulator, not reliable, Edgewalker is an occasional colored mana discount and nothing more.) What's worse is that the draw of double-tribal is having me keep marginal Rebels like Saltfield Recluse and Samite Censer-Bearer simply because they're both Rebels and Clerics.

-Is the Urborg, Tomb of Yawgmoth+ Cabal Coffers thing worth running in this deck? In mono-black, it's great mana ramp, but with this, the Coffers will only be marginally effective absent the Tomb, and vice-versa. Filth would help matters a bit by making the Tomb independently useful, but I'm not sure if that's enough to be worth including it. OTOH, I'm already mana-light and Rebels are extremely hungry, so I may be passing up something useful here.

-Anything else I should add?

Thanks.

Heartstone helps you with the rebels' ability costs, and Whipcorder keeps Emrakul & friends in check. Rings of Brighthearth is an interesting card with rebels, since for two extra mana you can search for another rebel or return one from the graveyard with Lin-Sivvi.

I don't think having the clerics for Scion of Darkness is worth it, I think you would be better off with Debtors' Knell. I like your decklist, it's innovative.

Ooh, hadn't thought of that. Let's see

-Saltfield Recluse
-Samite Censer-Bearer
-Edgewalker
-Dark Supplicant
-Order of the Stars
-Scion of Darkness

+Debtors' Knell
+Heartstone
+Rings of Brighthearth
+Scepter of Dominance
+Whipcorder
+Not sure, Marsh Flats maybe?

Are the changelings worth it? Some of them being more or less vanilla rebels.

You're lacking Conspiracy btw, fetch anything with lin sivvi Plus Black Market might be a good addition. Sacrifice 3 rebels, add 3 counters, profit
