Play a 5 cmc warp creature, then Neoform it into a Daring Waverider. Daring Waverider will flashback Neoform for free, sacrificing itself to fetch an Atraxa. This can happen T3 with a mana dork. If you are scared about removal, do it T4: Atraxa will likely get you a copy of Essence Flux, which you can use to protect it. It's very hard to get rid of the Atraxa afterwards, because every time you protect it with an Essence Flux, it will get you more cards, of which there will probably be another Essence Flux. I mean, it's top ten.
You can also transform a Thundertrap Trainer into an Occulus with Neoform, or into an Ouroboroid with Eldritch Evolution. This is especially practical if you need to aggro your opponent. Ouroboroid especially is pretty broken, basically autowins the game if your opponent doesn't have removal.
You usually want to grab a Mockingbird with the Gearhulk + another card. You can then cast Mockingbird for an extra flying Gearhulk that grabs you two more cards, getting rid of those mana dorks that are useless in the late game! Also, two Gearhulks, one of which is flying is not to be messed with.
Post sideboard, your Gearhulk will be able to fetch a ton of answers in Portable Hole, Haywire Mite, Giant Killer, Skrelv ect...
The 1 of Dragonmaster Outcast in the side is in case of a matchup that is really grindy. The Exalted Sunborns will make extra copies of the dragon tokens.
