i dunno
my two most common houses are shadows and mars with 4 decks containing shadows and 4 decks containing mars. out my 4 decks with shadows 3 are good and out of my 4 decks with mars 3 are good.
the houses seem pretty well balanced to me
I mean, I definitely have decks without shadow that are good. I just feel the Steal mechanic has no obvious counter unlike some other mechanics of other houses. My hope for the expansion is the introduce some kind of counter-steal thing.
Obviously, this is just based on my own experience. I have 6 decks, and a buddy of mine has about 8 and we rotate between them whenever we play. Shadow decks seem to be in the top tier. Shadow decks with Bait and Switch especially lol.
My favorite card in the game, though is in Dis. Without a doubt it's...Drumble
