Yeah, that sounds greaaat.Affinity can play Disciple of the Vault, sacrifice everything to Arcbound Ravager, and Shrapnel Blast you to death by turn 4. Goblins can also kill on turn 4 easily with Goblin Piledriver, Goblin Warchief, and Siege-Gang Commander. Elf and Nail can play Tooth and Nail entwined on turn 4 with the help of Vine Trellis and Vernal Bloom. All three decks, should they survive into the newer metagame, will still be capable of such antics.
My completely untested probably terrible idea that I've vaguely been kicking around is to try to semi-support a "oops it's storm!" deck. There are some storm spells (Empty the Warrens) comes to mind that could conceivably be played just for value. Combine that with a higher than average number of cantrips and whatever a generic term is for Treachery-like effects (untapping lands) and Karoo lands and you might go for pure value and wind up with random storm finishes.
Not sure how viable that is, but I conceptually love Treachery and friends and have also been wanting to include a Storm card that isn't broken.
Fresh Meat is also nicely held up with a pile of eldrazi tokens onboard, FWIW
RE:Caller: No Chord of Calling on Fresh meat?
Wait, actual upside: Pod my 2 drop, get 4 power. Kinda like Wakedancer, but good.
I guess this should maybe be in some cubes. Like Eldrazi Domain. Hmm...
