With Final Fantasy (almost) fully spoiled by now, here's an update to this Multiplayer Pauper Cube that I've been building since... god, I don't even remember when. I'd say around 2011 or so.

W
+White Auracite: a take on Oblivion Ring with the added utility of tapping for W.
U
+Dreams of Laguna: I like the card selection here and being able to fill the grave. It's not amazing but definitely useful and the Flashback helps a lot.
B
+Ahriman: this is a very interesting flier. Not only is it cheap, it can even recycle tokens or other creatures you no longer need (at a high cost, but still). Compare it to Deathgaze Cockatrice to witness first-hand the power creep (RIP)!
+Marlboro: the big bad from FF makes its way into the Cube! I just like the idea of bouncing it and maybe killing one or two players at the same time. It's a very interesting mix of ETB effects that can really hamper your opponents.
R
+Haste Magic: a strictly better Blazing Crescendo. Not much else to say!
+Hill Gigas: a mostly upgraded Lava Serpent.
+Laughing Mad: excellent card selection with Flashback to seal the deal.
+Sabotender: it's a fragile creature for sure, but one that can ping your opponents for a lot of damage if it stays on the battlefield. Reach isn't half bad either.
G
+Airship Crash: Cycling is one of the best keywords in the game really. This is just a strictly better Broken Wings.
Multi
Colorless/Others
+Adventurer's Airship: Remember Smuggler's Copter? The card that was banned in Standard? The new take on this card is an excellent common and a slam dunk for the Cube.
+Iron Giant: keyword soup monster that is actually decent!
+Lunatic Pandora: wait, this is a common?! The first corlorless legendary one at that! And it's great. Fueling the graveyard with Flashback cards and other stuff is already neat, but the icing on the cake here is the ability to destroy something for 6 mana at instant speed. Probably the best common of the set for this Cube alongside Adventurer's Airship!
