This is a generic Bant auras build, but with my own flavor.
Avacyn's Pilgrim helps set up earlier enchantments, allowing a turn two creature, followed by an enchantment.
Fencing Ace is one of the two creatures that win matches. His Double Strike makes a single Rancor absolutely terrifying.
Invisible Stalker is the other main hitter. Hexproof and being unable to be blocked makes him nearly indestructible. Throw auras on him and your opponent's clock is set.
Silverblade Paladin makes Invisible Stalker a better Fencing Ace. That's about it.
Abundant Growth is card draw and mana fixing. It also builds Ethereal Armor for cheap.
Ethereal Armor is probably the best Aura in the deck. It makes all your creatures massive. The First Strike is irrelevant however.
Rancor gives Trample. That's good enough for me. Fencing Ace+Rancor is six points of Trample damage. With 15 more auras, that's not going to be the only damage he'll put out.
Spectral Flight is simple. Gives Fencing Ace evasion and a little buff.
Unflinching Courage gives Trample and Lifelink. That makes both Fencing Ace and Invisible Stalker incredibly powerful.
Inquisitor's Flail is probably one of my favorite cards in the deck. The double damage dealt to equipped creature is irrelevant because Invisible Stalker can't be blocked and Fencing Ace deals First Strike damage.
The sideboard is simple.SBCurse of Echoes, when resolves, shuts down control decks. There are probably better options for this, but I personally like Curse of Echoes.
SBDetention Sphere... It's Detention Sphere, I don't know how to explain in. Really good spot removal.
SBNaturalize is good for mirror matches and other enchantment/artifacts that can prove to be troublesome.
SBNevermore stops Supreme Verdict on the play. If on the draw, after a Wrath, resolve Curse of Echoes. Simple.
SBPithing Needle is quite simple. Many cards can become empty cards after it. Planeswalkers, AEtherling, Drowned Catacomb etc.
SBRest in Peace for non-transformational sideboards in decks that involve the graveyard, but often, game 2, reanimator decks side out Unburial Rites and turn their deck into a mid-range decks, but it's just useful just in case.
