To get directly to the point, this deck seeks to get big creatures out or get card advantage using the Improvise mechanic. Now when the Improvise mechanic was first spoiled, to be honest, I did not think that this was a good mechanic at all, but when I was trying to build an Aetherflux Storm fun deck, I realized how many 0 drops standard has. With 12 0 drops and a few cheap artifacts, we can be casting big creatures as early as turn 1 and dealing 6 or 7 damage as early as turn 2.
Bone Saw, Cathar's Shield and Ornithopter - this deck is going to play a full set of these "free cards". It activates Improvise quickly and leaves up mana for other spells
Bastion Inventor - a big beater with evasion that we can cast as early as turn 2 or 3. Since it has hexproof and is a 4/4 creature, it can't be easily removed until midgame.
Sweatworks Brawler - now this is a card that we can easily cast on turn 1. It is a 3/3 with menace which means that we can be dealing 6 damage on turn 3 unless it gets removed.
Enraged Giant - you want a big creature? This is a 4/4 creature so it's really big. You want it to have trample? Yes this card has trample. You want it to be a hasty 4/4 trampler? Oh hell yes!! A creature we can cast on the early turns, and at best it can attack right away because of haste.
Freejam Regent - a 4/4 flyer that we can cast on turns 2 or 3. Since it has flying, we can avoid those pesky early drops our opponent have.
Herald of Anguish - now this is where the fun starts. A 5/5 flyer that we can cast on turns 3, 4 or 5. Plus it makes our opponent discard a card on the early turns. If that ability doesn't say value, I don't know what is.
Reverse Engineer - for those who want to play blue we have another cantrip. Downside is that it is a sorcery spell, but then who cares? It's 3 cards for two mana
Reckless Bushwhacker - since Improvise leaves us with many open mana, we can surge cast this creature up so we can deal a lot of damage
Shock - with Copycat/Angry Cat Lady/ Saheeli Rai Combo lurking around, we need this card to shut that combo down
Battle at the Bridge - an Improvise cards is possible to cost us only one mana. It can kill big creatures and nets us some life.
Tezzeret the Schemer - not only does this guy help us with the ramp, with its ultimate ability we can have 5/5 creatures everyday
Ceremonious Rejection - what better way to shut down Aetherworks Marvel, Dynavolt Tower and vehicles than to remove it completely before it hits the ground
Metallic Rebuke - a mana leak that costs one mana 'nuff said
Disallow - a counter that hits all kinds of strategies
Tezzeret's Touch - an ensoul artifact with a reanimate effect, gives our artifacts an added value. even makes Ornithopter a flying beater
Unlicensed Disintegration - with all the artifacts we have lying around, we're sure to get a 2 for 1 with this card
Tears of Valakut - getting rid of those fliers is a nasty business
Chandra, Torch of Defiance - has a great removal, ramp and if we hit her exile ability with one of our big CMC creatures, it would hurt our opponents a lot
Sweatworks Brawler - now this is a card that we can easily cast on turn 1. It is a 3/3 with menace which means that we can be dealing 6 damage on turn 3 unless it gets removed.
