After a night spending with this stupid card trying to proc him in every possible deck and make it stable i came up with a few idea, some are better then others.
The first one - oak vespyr.
You are basically running the same stall until wintertide + plate.
Your wincon is fairly simple - crash your opponent with snowman in the back procing value while you use your walls and aspects, and vespyr tokens /minions to generate up to 5 on the same and summon oak - by that moment, the game is over.
In the times you will not be able to finish the trail you can always use animus or embla as a finisher.
Grove can be switched with aspect of the mountain or 2× aspect of bear to make space for 1 more embla.
Thanks to @epicflygon i decided to try some sort of arca. Proc with oak.
While a little clunky - it works beautiful.
The way i played it - i used walls and aspects to turn then into beasts, while procing prismatic ill. + owl beast to use my illusions as a blocking device.
And again - when oak went out - zirix’s fate sealed.
P.s - i’ve never ceeated a good arca. Deck nor i ever prefered to play one so this deck mighr be able to use your ideas and critic, so is the vespyr one.
