Really awkward deck idea that revolves around stalling and setting up with Eldritch Evolution. First priority should be getting Brigid, Hero of Kinsbaile out as soon as possible and then attaching deathtouch to her via Basilisk Collar. With this, you can penetrate blockers or defend until someone blows up her or the collar. If you know a better, quicker way to set this up, please tell me.
If you don't have her in hand, hopefully you have a Eldritch Evolution and Strangleroot Geist in hand to pull her from the deck. when Strangleroot Geist gets sacked, it comes back with a +1/+1 so its a win win. Vorapede does the same when you are pulling out large 7 drops. Preferably, i would go for Elderscale Wurm first but if you have Natural Affinity in hand, go for Elesh Norn, Grand Cenobite for a one sided land wipe.
Typically, you won't be attacking until you have a 5 drop or Brigid out to cover your attacks. Since you'll usually have only one 5 or 7 drop on the field, it would be nice to have Sublime Archangel on the field if you already have Brigid. With Strangleroot, Kitchen Finks, and Vorapede not leaving the field after getting sacked, you can count on some exalted damage.
If you don't have Brigid on the field, there's always a plethora of Ghostly Prisons and Sphere of Safetys. If your opponent plays a low mana curve deck, evolve your creatures into Acidic Slimes to screw up their spending mana to attack. You also get a deathtouch creature that deters smaller attackers.
If you get a starting hand with both 7 drops or both Vorapedes, mulligan. That's just a very bad hand you don't want to deal with since you can only Eldritch Evolution from the library. I haven't found a solution from drawing big drops aside from blue cards shuffling them back in. Help with this aspect is needed.
If you are against a removal deck, sideboard the hexproof cards. Against a sacrifice deck? Throw in Sigarda, Host of Herons and evolve into her. Can't wall with Brigid since they run indestructible? use Bonds of Mortality. I also threw in some 7 drops in the sidedeck that are kinda neat.
