Brewing up a spicy Turns deck featuring Kefnet, the Eternal for 'free' extra turn spells. It's sort of a control deck until Kefnet drops, after which I'm digging for extra turns and getting value off anything else encountered along the way. The big blue bird is also the primary win-con because it's hard to race a 4/5 flyer when you're not getting many turns, with Niv, Explosion, and Ral backing him up and just being value.

I'm still not entirely sure on the control package, especially the sideboard. Counterspells don't quite work with Kef or Ral so I don't want to use too many, but it would also be dumb not to use them. The Maybeboard includes other ways of taking extra turns and some removal I considered. Riverwise Augur becomes an infinite combo with Kefnet and Sundering, because you can keep bouncing augur to put the real Sundering on top and just cast Kefnet's copies.
