Madness cards and smuggler's copter a-go go.
The deck can win on turn four against a goldfish, which is nice. I'm a fan of the Night Market Lookout + Smuggler's Copter
interaction, the lookout also comes down on turn one and effectively attacks for two on turn two which I'm in the market for. Remember that you can crew vehicles at any time, regardless of whether they're creatures and whose turn it is. Always tap your lookouts on your opponent's end step if possible.
Bomat Courier
+
Cathartic Reunion
, discard to cast reunion then sack the courier to draw the exiled cards before the draw happens, goes great with three or less cards in hand or of course madness.
I thought about having Unlicensed Disintegration in the main, the only reason it's not there is because if your opponent isn't on the board it's junk. Good against decks that want to gum up the board with blockers though, so swap it for
Incendiary Flow
if the match up calls for it.
The rest of the sideboard is guesswork, if you need to kill creatures Harnessed Lightning seems legit, and
Ruinous Gremlin
hits artifacts and crews vehicles/attacks. It might be right to run some number of Lost Legacy against Emrakul decks, but I'm pretty sure we just beat those by smashing face until there ain't no face left to smash.
I'm a little worried about the vehicle to creature ratio, which is why Fleetwheel Cruiser is in the side instead of the main. If that turns out to be less of a thing it might be right to swap out the Pia Nalaars or
Skyship Stalker
s in the main deck for Collective Defiance or the cruiser.
Chandra, Torch of Defiance might be amazing in this deck, in fact it probably is, but it's also like $40 and dies way to easy to vehicles for me to be comfortable dropping $160 on a play set before I see it working.
