Main deck
I think this is one of the most consistent mill decks around
1. the 8 merchants give you more access to the most important combo pieces which is diogo malaga elonge
2. you copy the diogo with mirror image or quicksilver mirror once you have copied 3 you can start milling for free
NOTE the one thing that stops you winning that turn is time out -- so be aware of this
-- time out doesn't matter on gauntlet so makes this a great gauntlet deck
3. you also have the standard moornful death cap option for another way to mill
4. if the mill option is not running smoothly you can switch to the beat down option and cryptic master is a really strong unit in the deck with a lot of relics in play
I feel the deck needs a 1 drop (cant decide which one) so that I have a potential turn 1 play into a turn 2 cryptic master proc
Market
The only really needed cards are
Moonstone mirror to keep copying severin or merchants
Severin the mad mage - as this is the main win con piece of the deck
and possibly
Bazzaar stampede as a finisher
the other 2 slots are flex slots but I wanted a way to get face aegis to protect mirror but also have a way of clearing small aggro while the deck gets going
