My Martyr Life deck that has consistent wins against all varieties of decks. The more realistic CMC of this deck is 1.77.
The Land:
4 Flagstones of Trokair - Great lands that not only protect you against land destruction, but you can thin your deck out by using the legendary rule to your advantage! Tap it to float a white mana, then lay another Flagstones of Trokair on the battlefield to send the tapped one to the grave, which triggers the land fetch from your library where you can get a Mistveil Plains or just a basic Plains.
2 Ghost Quarter - Used to destroy your opponents land. Good against Affinity when they're struggling for land, great against Tron, and a great way to remove pesky man-lands.
1 Mistveil Plains - It can be fetched with Flagstones of Trokair and its best uses seem to be send creatures with CMC of 1 to the bottom of your library before you lay a Ranger of Eos OR sending a Squadron Hawk to the bottom while always keeping one in hand, so you can constantly maintain multiple hawks. Having this land in your deck can also be great against mill decks.
14 Plains - Basic lands are important against Blood Moon strategies and I want to avoid having any more nonbasic lands.
The Creatures:
4 Ajani's Pridemate - One of my two heavy hitters in the deck. He can get ridiculously big very quickly with a sister on the field. Very hard for decks without targeted removal to deal with.
4 Serra Ascendant - Another one of my heavy hitters. This guy can be a 6/6 Flying Life-linker swinging on turn 2! Combos well with Martyr of Sands.
3 Soul Warden - Awesome 1 drop, the deck's bread and butter card.
4 Squadron Hawk - This little guy is little, but its a 4 for 1 that thins your deck out!
3 Soul's Attendant - Same as Soul Warden, just less hot.
3 Martyr of Sands - Capable of crazy blowouts. Will make burn decks scoop when you sacrifice her and gain 15+ life. Makes Serra Ascendant a beast.
3 Ranger of Eos - A great card to refill your hand and thin your deck out. You almost always fetch up a sister and a Serra Ascendant.
1 Aven Mindcensor - Great 1 of for shutting down Tutoring/fetching.
1 Auriok Champion - Great draw against Black and Red match-ups. Mainboard if you feel that Black and Red are popular at your local meta.
The Other Spells:
2 Brave the Elements - If a board state is stalled, this can be your way to get in lethal damage. Protects against cards like Pyroclasm, Anger of the Gods, and Whipflare. Allows for great trading opportunities.
4 Path to Exile - This is a great card that just ruin's your opponent's creature strategies and can deny some game-winning combos!
4 Spectral Procession - This card is great. Its 3 1/1 Flyers for 3 mana while being a CMC 6 spell, which is very relevant against cards like Eidolon of the Great Revel. With Honor of the Pure, these spirits can be great units to either defend or attack.
3 Honor of the Pure - This enchantment is nuts in this mono-white, mostly creature deck. Little guys becoming huge in Japan.
Sideboard:
2 Angel's Grace - This is a new choice to bring in against combo decks. Too often do I die to combo when all I needed was one more turn to win. I hope this card can give me the chance to turn my opponent's smile into a frown.
2 Ethersworn Canonist - Great against Storm and Living End.
2 Rest in Peace - Great against any deck that wants to use their graveyard to their advantage.
2 Stony Silence - Unbelievable against Affinity and GR Tron.
2 Sundering Growth - Great artifact/enchantment removal and you can gain a 1/1 Spirit Token with flying, making it strictly better than Disenchant.
2 Suppression Field - Shuts down combo decks using Splinter Twin & Kiki-Jiki, Mirror Breaker. (I believe it hurts Scapeshift a little as well.)
2 Ghostly Prison - Great card to have against lots of creatures. Works well to stop Twin/Kiki combo.
1 Leyline of Sanctity - Good for Gifts Tron and burn (even though we don't really need it for burn.
