-Edit- 5-30 First edit in a long time. I added in 4x Cartouche of Solidarity. I think this does enough vs blessed alliance and Liliana of the veil to be a great addition to the deck. We only lose 1 Umbra, keen sense (which i was going to take out soon anyway) and two copies of Gryfs's boon, which we already have two copies of spirit mantle to satisfy our evasion clause.
-edit- 2-13 added the leylines to the main. Everyone is doing it and really i lose game 1 on the draw against any thoughtsieze deck, so its actually a really good idea.
Green/White Enchantments.
Usually enchantments are awful, because you're putting all your eggs in one basket. And then they kill it and they get a 5 for 1.

But with this deck, you have all your eggs in one basket, sure, but the basket is untargetable and doesn't tap, and draws cards, and tramples, and first strikes, and doesn't die to sweepers.
One of your biggest fear is the black deck. They can make you sacrifice your creatures, or thoughtsieze you turn 1 so The sideboard revolves around making this matchup easier. As well as some hate to some specific decks. Tell me what you think! If your local store doesn't have many black decks (it's expensive after all) then you have much easier matchups and can tailor your sideboard for those decks. You can also run Dryad Arbor, so you can go get the arbor with a uncracked fetch to sac when they target you.
-After some testing, this deck has a very bad matchup vs Infect. It's usually just 1 turn faster than you. Mulligan aggressively vs this deck. Having a Path to Exile for their 10 damage poison attack will win you the game. (unless it's Spell Pierce'ed. I don't want to talk about it.)
4x Daybreak Coronet, 4x Ethereal Armor and 4x Rancor are 100% core and unalterable. The umbras are there to go against sweepers and i would suggest running 6-8.The rest of the auras are a bit more fluid. Spirit Mantle is way better than trample and well worth running. Unflinching Courage is probably the aura most likely to get sideboarded out, but it can be helpful against aggro.Gryff's Boon is another way to get near-unstoppable evasion and even costs one less than Spirit Mantle. I'm not sure which one i prefer, so I run a pair of both! Keen Sense could be an addition for more card draw, but hopefully your Kor Spiritdancers can handle that. If you don't have the dancers, I would definitely run 2-3 Keen Sense I would also consider subbing in Spirit Link to take the place of unflinching courage against aggro. If your meta is all damage, all the time, mainboard links over courages. If it's combo decks and infect, courage adds more punch.
This idea isn't mine alone, the exact decklist is, but the deck idea itself came from Reid Duke, who took 2nd in the 2013 magic Championship with this deck.
After some of testing, Good matchups include: Burn, Jeskai control, Blue white control
50/50 matchups, black white tokens, TRON
Bad matchups, Grixis control, Infect
If you're rich, or have 4x Horizon Canopy just lying around. These get subbed in in place of the Brushland But for now, not putting these into the deck cuts the cost almost in half.
