Felidar Sovereign. Mythic Rare from Zendikar. I still don't think you need that much ramp

it really is just for the color palate. i believe the biggest win condition is Test of Endurance. there was another card we don't have that's the same thing, but for 40 life instead of 50. 

with this deck, she'll play angels with flying, gain life, and mana ramp to do it all fairly quickly.

Its definately a good start. I was just confused about the purpose of the deck.  Siguarda is not that great of a beater for a win condition, so you kinda just have to use her color palate.  She's actually probably the least useful of the three as a commander.  Gisela doubles up damage, so thats beastly.  And Bruna can sneak in auras, so you can snipe a win with commander damage.  But Sigarda doesn't have any real punch.  She just counters Thraximundor and eldrazi

i think we did a good job putting this deck together. especially since we only used cards on hand. davey and i told her that it can get alot better, but she'll need to spend the money to beef it up more.

You could probably cut the first ten creatures on your list.  I'll copy the decklist and modify it

If you want to do a lifegain win condition, you should look into Felidar Sovereign, Serra Acendent, Soul Warden, Essence Warden, Archon of Redemption, Blazing Archon, and Rhox Faithmender for creatures.  You probably don't need as many instants as you have that give protection.  If you want protection, get a Mother of Runes or the Circles of Protection.  You should put in Fog effects too, since that will help preserve your life.  Some other good enchantments are Angelic Chorus, Cradle of Vitality, Mark of Asylum, Sigil of the Empty Throne, and Luminarch's Assencion.  Some flicker effects could help too.  You probably don't need as much ramp in the creature area as you do.  Stick with rampent growth type cards, or primeveal titan (especially with flickers).  You want to make it hard for other players to attack you.  So witchbane orb would be good. Also acetecism.  Anything that gives you (the player) hexproof.

Yea, Davey and Tyler were arguing about that. I wanted to make it similar to yours and win with Angels or something, but the win condition is to gain enough life to win. (Test of Endurance)
