Yggdrasil 2 -
This is a little more aggressive than my last Yggdrasil deck. I've added Morgiana to offer some strong filtering with Familiar/Foment/Refuge. Gwibers pair with the smaller drops and the Wind Sprites for a heavy-hitter that is cheap and flies. Celestial Wing Seraph gains life and grabs Lucifer out of the deck for removal and more life gain.
The rest is pretty self-explanatory, so let me know what you think!
