Sanguar Queen (expedition #1)

I have over 80% win rate with this deck and it was the only deck I got 7 with in the expedition event.
Remember the damage from the Argenport Instigator and from Street Urchin also work for the Sanguar, so you will be playing Lurking Sanguar on t2 or t3 very often. Finish up with Bandit Queen or Rally from the market.
The Repeater can help you attack with you little guys even when the opponent has bigger units and to score some extra dmg.
The monument in the market can be used either for a black influence to play Tasbu, as a fourth power if you are desperate or as a midgame lifesteal unit, great if you are racing for dmg.
Xo can be used as a late game decider or if you need an extra card.
Dizo's office can be traded for a removal like deathstrike.
Dark return and Combust are pretty standard market cards.
