PLEASE LEAVE SUGGESTIONS IN THE COMMENTS - HIGHLY APPRECIATED
This deck is really challenging to play and I do not claim to have mastered it. Running 8 merchants allows you to trade a lot of cards away which you expect not to need. It runs a lot of 2/3 ofs so you do not rely on your draws but rather on your decision what you think you will need so here are a few tips:
1) Haunting scream is NOT worth it, past 30 games it was never deciding the game.
2) If the opponent is dumping everything on the board just play hailstorm or cirsos choice even if it means sacrificing jennev merchants (Playing them can also lure the opponent into putting everything on board -.-)
3) The deck does well against most matchups but TJ / Temporal Control seems to pop up again more and more often so make sure to keep unseal and rindras choice in hand against stand together/ aid of the hooru / etc.. Dump your removal in the Market against Unitless but keep Equivocates for your own units.
5) If you put Circo's Cleaver on your units they will keep killer after they die - keep this in mind as you may want to dark return them for an instant attack.
6) I suggest rain of frogs against Icaria, Kenna, and Witching hour decks, as for the first two I suggest you wait until they play their own merchants (if you have sth else to play instead obv.), otherwise they will simply grab it after you used rain of frogs.
7) Lastly, I'm currently not running banish because I seem to always beat token decks on board before Obelisk becomes a problem, and crown in 2018? Mask decks also rely too much on parliament/ aid of the hooru/.. so keep up unseal or rindras choice
