So with the new cards introduced in Price of Power, NG has been able to consistently thin the deck to 3 to 0 cards in Round 3. With this in mind I decided to mess around with an old Daerlan Soldiers swarm with Vreemde finisher. Here is a link to the deck
What makes this deck interesting is that with how much we can thin, we can abuse any card's deploy with Decoy. With the core of Blightmakers, Mage Assasins, Roach, Affan and Dead Man's Tongue you'll always get your deck down to 3 (often even less with other thinning cards) cards by Round 3, meaning that with your leader, you'll always be able make it so that your deck contains no units, meaning that when you Decoy unit, it will replay it. Imagine playing two Yrdens as your two last cards or any other card with devastating deploy effect.
What does this mean for future expansions?
If they ever release a card that is NG or Neutral that has really good deploy effect that is balanced by having low power (like Yrden), this combo can easily abuse it in Round 3. Now skillful players will be able to spot this deck in the future and counter it accordingly (winning round 1, bleeding round 2), but less experienced players might not and therefore have bad time with it (and probably complain on reddit as you do).
At the moment it doesn't seem that busted, but who knows what the future might hold
