I am having a lot of success with this deck. There doesn't seem to be any unwinnable matchups however it is gauntlet so you get screwed sometimes.
The market is a little weak. I really only ever pull the mask (overwhelm works very nicely in this deck),
Moonstone Vanguard, and
Striking Snake Formation
Generally you want to draw
Alessi, Combrei Archmage and
Awakened Student
And a cheap spell or two. Be patient, if you are playing against torch or shadow, it's good to wait until you can buff these two or at least play multiple on the same turn.
Stand Together and
Sword of Unity are straight up nuts in this deck. Try to use stand together on opponents turn when they try to kill a key unit or attack with something you can dominate. Sword can be tricky, I always want to wait for 6 power and a full board, but often will drop it on a unit with endurance or aegis for the lifesteal
