willows - A Sphinx in red? You maybe ought to have picked a different creature type for the red entry - that's really strange. Looting on the hit is certainly something a red Sphinx would do, but the whole Chandra Ablaze-style pinging thing might be too good. Anyhow, on a 3/3 for 3RR it's interesting and strong and I think it'd be okay.
Socrates - Leviathans in monoblack are unaccountably weird. I like the whole commit-to-a-color thing that I suppose got borrowed from Harbor Serpent. As it is it's a good Limited uncommon (because that's where discard and landwalk are most relevant), spesh in mirror matches.
The Angel of Elysium - One, colorless + colorless does not really a mirror make, even though one of them hates on other colorless things and the other on multicolored. Two, this is insanely, insanely, insanely overpowered. Sun Titan is a very strong card that costs 4WW and can only reanimate half the permanents this does with a restriction to low converted mana costs. Swing with this once and it's probably game.
I'd like to participate this month too. Anyone want to take a relative newbie under their wing?
