This is currently my favorite creature combo deck in Modern. It backs up the infinite combo Kiki-Jiki, Mirror Breaker threatens with an aggressive beat down plan. In addition to finding our combo pieces, Eldritch Evolution also lets us find different utility creatures in different spots. Just keep in mind if you try to evolve into a Bloodbraid Elf you will not get a cascade trigger!
If you would like some sideboarding tips with this deck, you can read my article about it on CoolStuff Inc here.
