Woo! A bunch of people have been drafting my list on cubetutor. I'm fairly pleased with the results so far. Here are some of my favorite sample decks from the last few days:
Pick a Jace:
Jace, Architect of Thought
Jace Beleren
Jace, Vryn's Prodigy
Jace, Wielder of Mysteries
Then pick a NotJace:
Kasmina, Enigmatic Mentor
Narset, Parter of Veils
Mu Yanling, Sky Dancer
DOMINARIA is the most beautiful mainline Magic set that I've ever drafted. It's got everything you could ever want out of a Magic set. Slow, grindy value engines! Weird sideways aggro strategies! Combo! Goofy build-arounds! 5c nonsense! It's the only set I've bought gems on Arena to play more of...
I just love both these cards and would find a different cut to run both.
Edit -
I like both of these way better than Abbot of Keral Keep, for instance.
It's very slow and the cost is real, but the payoff was absolutely worth it at least in the two sealed decks I had it in. I have no idea how it would be in anything outside core set limited. I suspect it doesn't get there unless you're super low powered or aggro is non-existent.
I'm on Thundermaw here. It deals spirit tokens and faerie tokens cleanly and it always gets in for the first hit. Plus, I just think the card is a classic. I have a soft spot for it. Every pushed hasty dragon is a Thundermaw reprint in my mind.

Okay, so after one day of playing with this guy on Arena, I'm able to confidently say that he is the Truth. Now granted, there needs to be at least a bit of density of elementals around, but the floor of 3 mana Coiling Oracle is perfectly fine. This thing with Young Peezy or...
I mean, it's very powerful, possibly the best card for limited in the retail set, but I think GRBS is pushing it considering the amount of mana you have to invest. If you can't find a way to deal with it before they put 8 mana into it, you sort of deserve to get wrecked by it.
The executioner was executed. So you have the spirit of the victim as well as the executioner itself. The executioner can then use its ability to execute someone from beyond the grave.
EDIT -
Oh, there were more pages where this was already explained.
