I think you could cut the Arbor Elf s for Experiment One s.

+1 to you and Sigarda, Host of Herons is better for sideboard for main use one more Oblivion Ring and one more Thragtusk .

@Old_ManWhile I appreciate your like and value your opinion, sigarda is a key part of this deck that has won me her weight in games. If she is allowed to resolve, which because of the caverns she does, it changes the flow of the game. I am deciding whether or not to keep ajani. If I rule against it, I will have two slots open to consider and test your suggestions.

I would maybe drop the ajanis and add at least one more Rancor , and maybe add a fourth Cloudshift . You also might want to think about getting a few Silverblade Paladin in there. Those bound to a mana dork with a bonds of faith or rancor become a significant threat T2 or T3. Then you can Cloudshift them out at bind them to sigarda or even better avacyn. I like it though. Plus 1 from me. I also have a humans angels. Modern though not standard, check it out; or any of my other decks.

As much as I wish it wasn't so, Avacyn needs to go. As an 8 drop she simply doesn't win you the game the turn she comes out like an 8 drop should. There are much better angels to put in her place like Angel of Serenity .

Thank you all for the suggestions. They are really helping shape the deck into a competitor at my FNM. Please continue to let me know what could make this deck the best it can be.
