Poison decay deck I used to help qualify for minecon. Helped me when I was scared of running my aggro growth deck into a bunch of spikey. Its value deck. And I dont think the list is right yet. But for some reason no one is playing poision decay. Which imo is very powerful again.
This deck is basically just stall with all your might, eventually just out value your oppenent and take over the board, chip at idols a bit, and then kill your opponent with Neccro. One halls. Halls is slow and this deck is slow already. Losing a turn is a huge deal when you are already slowing killing things with poison. So playing it is risky in most match-ups. I play it because some cause match-ups I want extra copys of certain cards. (Like extra lanquid +unbinds vs energy (to kill structures) or extra neccros vs another control deck)
