Very fun deck. Can substitute 2 voice of the speaker for 2 more seek power if you prefer. I prefer to use them for early board torch takers and something that can provide an extra card I can put in the market.
Amaran Stinger and Rhysta make a big contribution to the early game tempo.
This deck is great against other midrange or removal pile type decks. You can back-alley something that won't impact the board based on what you are playing against and then Subvert 1 of the two cards they may have left over.
Subvert is NOT a 1 for 1. It can typically be a 2 or 3 for 1 in this current meta. Time it as best as you can. If they play a merchant with one card in hand, you just take it right away. People do not see it coming.
If you can't discard a unit from their hand with Vara's choice or you are not gaining ground, tempo the units they play back into their hand. If you hit with Amaran Stinger early on, a scorpion or two can usually bait more removal or answer a card they play.
Of course if the game drags on, you have the market strategy based on how things are playing out. The deck has a lot of strength, affordability, and variety.
Feedback always welcome. Have fun!
