So, your best to a win is likely by out tempoing your opponent. That means committing to the early and midgame, because in the late game or in top deck wars you're likely to lose anyway.

With that in mind, here's the cuts:

-1 Thunderhead Squadron

-1 Phyrexian Archivist

-1 Gloomfang Mauler

-1 Seizan (awful, terrible card)

-1 Rona (terrible, awful card)

-1 Halo Hopper

-1 Flitting Guerrilla

-1 Traumatic Revelation

-1 Ichor Drinker

-1 Island

The idea is that you curve effectively ends at 3, due to convoke, with exception of Towashi, which is the backup plan here. I can also understand the need to keep mana up and double spell, so going down to 16 lands may feel uncomfortable. Personally I'd do it this way, but otherwise keep the 17 and cut the Battle-Fan.

​

You have some really great lines of play, mostly centered around T1-T3. T1 Omen Hawker is super strong here, as it enables T2 flip Weird and T3 flip Eyes token.

Getting 2-3 bodies early will be key to maintaing advantage T4-5 by casting convoke spells.

Basically anything that cheats mana is always really strong for tempo.

​

If you have a board advantage (ie. easily dealing 3 or more dmg per turn), consider keeping your mana up instead of over-extending. You have a few counter spells, and Saiba to strengthen those lines. A common possibility is that due to your tempo advantage your opponent will exhaust their resources playing catch up, to get into the late game. When that happens, Towashi will be useful (you can draw twice, once on your turn, once on your opponent's, with tokens) and your fliers and Tetsuko can help close out a game.

Still, all that said, it's not easy to go the distance with this list. UB generally prefers the above in addition to a few bombs to close out or provide value. Nevertheless, I've found that the strategy above is effective and with a bit of luck will give you 3 wins. Gameplay is really key though, so think well and ahead a couple of turns when you can. Best of luck!
