The is a standard green/white ramp beat down deck. 8 one drop ramp creatures mane up most of the first 2 or 3 turns plays. The main idea of the deck is to make you creatures next to imposable to remove from the battlefield. First up is Avacyn, Angel of Hope is the main work horse of the deck, she makes worldslayer not a death sentence for yourself, and keeps you ramp and other creatures stay on the field.
Asceticism is hexproof for all. This the the main combo so all your creatures are indestructible and hexproof. This combo leaves very few cards that can remove them from the field. The sideboard is filled with cards that deal with the few cards that are dangerous.
Sigarda, Host of Herons; she is here to deal with black control decks, mainly Killing Wave and Liliana of the Veil and any other sacrifice creature card. She is in the main board but will be switched out when needed.
Angel of Jubilation; she is here to stop birthing pod decks, as well as many New Phyrexia cards.
Grafdigger's Cage is there to stop Blue control decks mainly Snapcaster Mage. It also stops most Zombie and all reanimator decks.
Melira, Sylvok Outcast; is for stoping Black Sun's Zenith, Inkmoth Nexus Kessig Wolf Run decks and all infect decks.
Stony Silence is to stop white control decks with Sundial of the Infinite and Mimic Vat.Stony Silence also should be in vs red burn. Mimic Vatand Vexing Devil deal a lot of damage and is shut down by this. Shrine of buring rage also gets shut down.
Nevermore is there to cover anything else, but mainly it's here to stop White control/beat down/ miracle decks with Terminus.
On a side note Primeval Titan is not in the deck because i do not own one, and i do not believe that it will be returning in the Core Set 2013.
