Here is a link to all the downshifts. These are the ones, that catched my eye:
-Deranged Whelp: The predecessor to Goblin Trailblazer, which I really like. Definitely cubeable.
-Morkrut Necropod: 6 mana is obviously alot and the downside seems kinda bad, but from experience I can tell, that this card is way better than it looks. If you are willing to pay 6 mana a 7/7 Menace is certainly massive. The Menace usually counter balances the sacrifice effect as your opponent can't really take a lot of hits from this and is forced to double or even triple block this quite often, which is of course devastating, because even if you manage to assemble 7 power of blockers any removal (which I heard black has quite a few) will be an absolute blowout. If you are looking for a 6 drop in black, this one I can definitely recommend and cubeable.
Honorable mentions:
-Gisa's Bidding: A decent madness card.
-Ravenous Bloodseeker: A very nice free discard outlet in red. Very good for enabling Madness.
-Imprisoned in the Moon: Downshifted from rare. The type of removal is quite decent, but experience has shown that 3 mana is a lot and also you don't want to ramp the opponent, otherwise Minimus Containment and Utopia Vow, would be more widely played.
the downshifts are arena only. so if you really want to stretch your pauper rules, you could just add anything you want and make a "pauper powerlevel cube" i guess.
me personally im kinda inclined to make a "true paupercube" which doesnt allow any cards from a higher rarity at some point. pauper feels more like peasant now, compared to where i started.
