Katra Ambush

I wanted to toy a bit with Endless Nightmare and see if I could get some recursion from it reliably. To ensure we have enough power on hand I added Azindel, the Wayfinder, Ayan, Dark Conduit, and Battery Mage. I wanted Grodov's Burden for it's ability to spread abilities around and buff up our Endless Nightmare's even if they can't directly benefit from it. It combos well with the Aranha from Gnash, Desert Prince and Scorpion Wasps, or Desert Alchemists you can spread a lot of killer, exalted, deadly weapons this way. Flamebathe Reformation and Immortalize can add exalted to our multifaction cards and the former can kill off creatures early so they can be reclaimed from the void when we have a proc (Endless Nightmare) or a full board. Memory Dredger further aids the recursion. Both Katra's and some more ambush cards round out the mix.
