Absolutely
love this card. It's a Kiln Fiend that forces you to cast a spell pre-combat to attack, but it has the potential to deal lots of damage if coupled with some removal spells. It's even a common in this small set, so you're likely to see it often in drafts.
The golgari mythic looks fun, if a bit overcosted. I'll gladly try to get some copies for my pre-rotation BUG self-milling deck, though. Stuff like Deathrite Shaman could help remove unneeded cards while getting an use out of them.
I don't care about most orzhov cards other than Obzedat (I love how it blinks itself), but I can see the dual protections and lifelink could make it quite an annoyance for black or white-based decks, and even Gruul needs to 2-for-1 itself to kill it (block + burn, two burn spells or sacrificing a Reckoner). Personally, I'd rather have quirky cards (even if they aren't that powerful) than powerful but straightforward ones like these.
I also came up with two new concepts for YMTC, which are tangentially similar to Exquisite Corpse (and a lot simpler):
Flesh Processor BB
Enchtantment
XBB, exile a creature card with converted mana cost X from your graveyard: Put a 2/2 black Zombie token onto the battlefield with X +1/+1 counters on it.
It could also work with any graveyard, but then I guess the ability would have to cost more to activate.
Life After Undeath 1BB
Enchantment
XBB: Return target creature card with converted mana cost X from your graveyard to the battlefield. It becomes a Zombie in addition to its other types.
Whenever a Zombie would be put into your graveyard from the battlefield, exile it instead.
This one reuses creatures directly, sort of like Chainer, Dementia Summoner, only it asks you to pay the creature's CMC to make it harder to break.
