[AuroraOpen#3] GY Spirit of Sac
It is a more defensive version of GYsac, than pre-balance patch when Salmons and Sky Yaks were core cards of GYsac. But with the patch and Salmon not being a sac target anymore and Sky Yaks on 4Faeria i dont think they just decrease consistency in GYsac and can make your draws really awkward (but maybe they still are good enough- i just felt like trying something different).
I always try to get to both wells asap, try to confront my opponent on the side he chooses to advance towards me and ideally have a Spirit of Rebirth collecting on the other side. Which land you start off with depends on your draws, ideally you want to sac something t3 if possible and deserts next to wells for Wind Soldier lines.
For my starting hand i search for one sac target (Village Elder or Bloomsprite) a t1 creature like Bone Collector and a creature that sacs your stuff (Assassin, Demon Wrangler), but depending on your match up sometimes it is good to keep the Last Nightmare, or mulligan hard for Eredon or Stalkers. You never keep Soul Eaters ;)
Overall it feels like a very consistent updated version of Maihems & Kanthiks GYsac from MC XI.
