I started with Umbra Mystic, looking for a way to make totem armor more interesting as a focus. By adding in a couple copies of Elixir of Immortality and 18 enchant creature cards (for the 20 creatures), I was able to make a pretty cheap and fast deck that can stay alive nearly indefinitely and gain a ton one life, all while recycling the graveyard. Double strike is interesting when it matches up with Celestial Mantle. Luminous Wake on almost anything, but especially a Goldenglow Moth, is fun. I don't know quite how this will fare in the wild, but it looks fun for now. The 20/5/10/3/0/2 curve averages 2.10, but that is brought way up by the Celestial Mantles at the 6-spot (1.89 otherwise).
