Even Xenan Ramps

Even Ramp deck in Xenan faction with a Nightfall subtheme. It's weird (but oddly liberating) not having to worry about what to put in the Market. Breezed through a Gauntlet run (boss: Helpful Horns) with it, maybe there's potential here.

I'm running Caiphus because I like the card, but probably it'd be better to run some numbers of Annihilate and/or In Cold Blood in its place.

Encroaching Darkness feels good as a one-off, but a second Nullblade would be nice (I only have one).
