I was curious about this at first when I saw the new cards. I thought a buff deck might be doable; use Katrin/PlateA/Aeon/KP

Ok so here's my current deck:

1x Zhanna Mist
4x Puwen Bloodhelm
4x Priest of the Light
4x Tainted Oracle
2x Earthen Protector
2x Aeon Stormcaller
4x Tidal Wave
4x Focused Prayer

I just had a crazy thought… what about Voice of Winter?

I get the feeling they wouldn't be super competitive, but the idea seems worth exploring because it's finally do-able.

Core Cards:
1x Zhanna Mist
4x Healing Touch
4x Priest of the Light
4x...
