x 1 Cut this guy as he is quite ineffective Angelic Overseer
x 3 Cut these because they are too slow and you won't always have a human Avacynian Priest
x 2 Gideon's Lawkeeper is better than this guy, so cut this guy for 1 more lawkeeper and something else Bonds of Faith
x 3 Run Oblivion Ring as removal and Angelic Destiny or swords as self enchantment - probably both Champion of the Parish
x 1 - Either a 4 of or a 0 of depending how you find him Doomed Traveler
x 1 Definitely a 4 of. Elite Inquisitor
x 1 I'm alright with this just because the 2drop spot is bad for humans.... I run Grand Abolisher myself. Probably 4 of though Elite Vanguard
x 1 Run 4 of or none of, test with the other 1drops and see what you like best. Fiend Hunter
x 4 Probably a 3 of because not all decks run creatures Geist-Honored Monk
x 1 Too high of a curve, cut this. Gideon's Avenger
x 2 Maybe alright, I probably wouldn't run him since there are better and more reliable 3drops Gideon's Lawkeeper
x 3 Great card, I run 3 but you might want 4. Honor of the Pure
x 2 DEFINITE 4 OF THIS CARD Invisible Stalker
x 2 Probably better in another deck. Mana Leak
x 3 Always a good card, depending how you play. Mentor of the Meek
x 3 Some people like this, some don't... I find that you normally don't want to spend the mana, and this guy isn't strong either way. Mirran Crusader
x 1 Definitely 4 of Oblivion Ring
x 2 Maybe increase by 1, switch with a fiend hunter? Psychic Barrier
x 1 Don't run because of double blue, cut for another mana leak or creature or something Shrine of Loyal Legions
x 1 Probably better in the sideboard as a card. Silver-Inlaid Dagger
x 1 Replace with a sword or Angelic Destiny or something Solemn Simulacrum
x 1 Not really necessary in this deck, replace with a better 4 drop named Hero of Bladehold
Moorland Haunt x 2 You can run between 2-4 of these, depending how you like it.
Glacial Fortress x 4 Great
Shimmering Grotto x 2 Unnecessary for this deck, put in 4 Seachrome coast
Plains x 10 Cool
Islands x 2 Cut 1 or both as it's normally unnecessary.
Run 23 land or more, I'm running 4 Seachromes, 4 Glacials, 3 Moorland Haunt, and 12 Plains
Morale of the story, run 4-ofs your good cards like the Mirran Crusader, Doomed Traveller, Hero of Bladehold (Which you will be putting in :P), and run 3 ofs things like Fiend Hunter/Oblivion Ring/Mana Leak.
Try and find what 1/2 drops you want to play with although you need 4x Honor of the Pure and 4x Doomed Traveler.
