Praxis Mid/Aggro Expedition (Masters)

Finally hit Masters in Expedition this month using this deck. Honestly, the entire month was frustrating (probably because I refused to play Cultists). I was one win away 7 times before I finally made it, after having dropped all the way back down to D3, using this deck exclusively.

Choices:
Borderlands Lookout - broken 1 drop.
Char - takes out early units, and especially allows Borderlands Lookout to trade up with Varret and other Lookouts.
Ghar - This was one of my favorites. Particularlly good against Hooru, but also great if you can shift it turn 5 when they have 4+ cards in hand, and also against Karvet. Allows you to push damage early.
Conflagrate - The only thing close to Torch. Save it for Varret especially when you know it's coming.
Kairos' Choice - My absolute favorite. Using it to kill something is fine. But against Hooru, letting them play a bunch of curses on a unit, then bouncing it back to hand on your turn with power from Eclipse Dragon wins games. Also, use it on Eclipse itself when someone tries to kill it. Don't forget about that ability, it can create a huge advantage.
Trail Maker - Allows ramp into Eclipse Dragon and Venom Rider, but mainly fixes influence to get Ramba out.
Edict - Mostly there for the Incarnus' of the world, but also for spell negation, and bouncing units back AFTER a weapon is played on it.
Gnash & Ramba - I mean, honestly. 4/4 units are very hard for a lot of other decks to handle efficiently.
Scorpion Wasp - efficient removal that almost nobody plays around, and if they do, it is still to your advantage. Forcing them to use removal/fast spell on a 3 cost 1/1 is great.
Venom Rider - Hard to block, always trades up. But the ultimate is game changing every time you use it to take out something like Ilo & Miza.
Eclipse Dragon - top end finisher, and the 3 power to use on your turn is huge, especially for Scorpion Wasp.
Market - Bore for curses and Exalted weapons, Edict for obvious reasons, Burn Out for reach when the board stalls (not quite Obliterate, but it can win games also - conveniently can deal with Karvet), Combustion Brawler to save you from lifesteal (again, Karvet - damn that card is busted), and also shifting it gives it unblockable to close out games. Finally Soulfire Drake to finish games, and also to give evasion/charge to your deck (use with Ramba's ability, it's quite fun).
Power Base - not using too many emblems because getting to 6 or 7 is sometimes required for Soulfire Drake and Ramba's passive ability.

Hope this helps someone else get there.

Best of luck!
