Abuse the AI with Deadly and fast spells.
Usually you always get Vara from market, but Deathstrike if you have the board already isn't bad. Setback for the tokens deck, and I actually took out Burglar for Flamestoker because it just wasn't happening often enough. The AI is pretty stupid with not sacrificing units it perceives as 'valuable' but then can't deal with the 5/6 Vara. Slamming it to get rid of a 1 or 2 mana dork isn't bad either.
Hardest match is probably the Hooru Unseen deck or Praxis Tokens. Keep the Hooru from a big flier and you should be able to race them by abusing Deadly. Having a fast effect on hand to keep your blocker alive from their Killer unit can be good. Tokens it's important to wipe their board with a Plague or a big blocker on the ground with removal/silence for their creature pumps. Obelisk sucks, but you can usually fight through it.
I tried to use as few rares as possible as well as keeping the shiftstone cost down by relying on Vara and Impending Doom as a wincon since I didn't want to spend shiftstone on a gauntlet deck. But this is very consistent with not being power screwed or flooded and relatively cheap.
Weakest cards are probably the 2 drops. I don't really like the SS influence requirement on 6 of the 2 drops, but playing them on later turns isn't that bad. There's a new 1/2 deadly, Kerendon Steward, you can substitute in so you don't need one of the campaigns for Ripknife. I also used to run Workshop Tinker that was decent to prevent flood. Lethrai Target Caller is honestly one of the weaker cards though it is a good common and the AI avoids blocking Deadly+Quickdraw units. You can sneak in a ton of damage while holding the ground with a Deadly or big unit. Then finish it with a trick to blowout the AI when they finally block your units.
