Guile,
Spelljack,
Draining Whelk,
Chromium, the Mutable
That's me. More creative this time with fun stuff like a flash uncounterable 7/7 flyer and creatures that counter. Cute, but I forgot about all sorts of stuff and it ended up a lot weaker than I had hoped.

Chancellor of the forge,
Counterflux,
Torrential gearhulk,
Aethersnatch <- disagreement here
OTP and OTD I plan to cast Chromium, discarding Guile, at the end step of your first turn. You could discard Gearhulk to Snatch it then, but I'll just discard Spelljack and make it a 1/1 hexproof
until end of turn (considering your remark in your results post, I think you missed that clause). So you wait in order to be able to use the Gearhulk and have a body
and threaten Snatch. During my turn, I'll draw Guile again and attack with Chromium for 7, putting you to 13, and then pass the turn. Now you can make Gearhulk by discarding Snatch and then cast Snatch. In response I discard Guile to make Chromium a 1/1 hexproof UEOT. Next turn, the board will be my 7/7 flyer against your 1/1 token and 5/6 hulk, with you on 13 life, so you'll die in two turns, so I'll win that.
Now let's go back to your first turn. As I'll win the line above, you have to do something on your first turn. But if you start by discarding Flux to make the Chancellor, you won't have Flux up for when you try to Gearhulk-Snatch. This line will net you 2 more 1/1 haste tokens though, so let's have a look. You make the Chancellor and have a 5/5 and 3 1/1 haste guys. You attack with the gobbos. Let's see what happens if I just take the damage and go to 17. At your end step I make Chromium. You don't do anything, because you'll need the body of the Gearhulk and I have Whelk and Spelljack up. On my turn, I draw Guile and attack for 7 (d=13 / A=17) and pass. On your turn, if you discard Snatch to cast Gearhulk, I'll Whelk it and get a 7/7 bodym so you wait and try to race. You attack for 8 (A=9 / d=13) bneeding two more turns to kill me, while Chromium also needs two turns, but it'll be my turn next, so I win that race as well.
I don't see other lines that make sense, so think I win 6-0 here.
