I preffer Platinum Angel + Robe Of Mirrors/Hannas Custody. They all work but cost lots of mana and doesnt kill your opponent.

I have some considerations to make:

- I think you should run all 5 moxen and about 16-18 lands, including 4-5 Fetch and 3-4 Wasteland/Mine.
- Id cut 2 Duress and 2 Hymn for 4 Thougtseize and 2 Oxidize for Echoing Truth/Wipe Away/Repeal.
- Enlightened Tutor, Mercy Killing and SDT are not good options. Id cut them for Lat-Nams Legacy/Scroll Rack and some Mana Drain/Negate.

I also think that you're too afraid about your first game in the match, you can try to antecipate the Tezz/Vault metagame and you can be right but you also can be very wrong and then play with the wrong deck at the wrong place. If you think that your metagame will be full of Tezz, open 6-8 slots in your sb for hate (Rack and Ruin, Pithing Needle, Krosan Grip, Oxidize, Shattering Spree, etc). Using artifact hate in your maindeck isnt the best option cos it reduces cards for FoW/Misdirection and makes you draw dead cards in some dificult games like Fish and TPS/Long.

When you decide to play Hellkite Oath is pretty much important to kill the oponent in the 2nd turn after Oath or Tinker resolves. Inkwell Leviathan is a very good card but it can slow your game down and give your opponent one more turn to win.

Id cut 1 Misdirection and try to use Ponder.
Have u considered Dimir Cutpurse over Augury Adept?

No Painters or Oaths in your metagame?

Im in.
