I brought in the Slippery Bogle over the Gladecover Scout as its more flexible in the 1 spot.
Also removed Rancor for Ancestral Mask. Reason being if my creatures are unblockable trample really doesn't come into play id prefer the +2/+2 bonus for each enchantment it really ramps up the damage.
I added Aqueous Form making other creatures unblockable, letting me scry 1 and ads to Ancestral Mask. this combos great with Curiosity for the scry and draw and Sigil of Sleep keeps their creatures off the field.
Added Troll Ascetic for the three spot. If Sigil of Sleep doesn't keep creatures off the board fast enough he will be my blocker, staying alive with regenerate.
For the end game:
Right now I'm going AEtherling but if I use his exile ability all the enchantments would droop off. He would combo better with Rancor because I could keep putting it on him. Ill keep playing with this. if he doesnt work out I have Plated Slagwurm in the wings., its a little more expensive but an 8/8 Hexproof for 7 is awesome.
Other options:
If Im playing some kind of control/burn deck I will pull out the Witchbane Orb using Simic Charm to keep it safe.
For super aggro that just throw out creatures I'd swap in Ambush Viper Coastal Piracy and Lorescale Coatl maybe even Fog.
The Ambush Viper with be for defensive plays to kill creatures Sigil of Sleep or Simic Charm cant bounce. Coastal Piracy and curisoityprovide a lot of card draw helping me keep on top in the card management game and pumping up Lorescale Coatl that unfortunately isn't hexproof but would get big quickly. Spider Umbra would be a good way to protect it and make it more versatile, but what comes out?
