Posting this for a discussion in another thread, so advice/help is not really needed. Always welcome though :)
This is my current mono white deck. It started out as human tribal, which I'll post an example of below, but this is what it changed into.
4 {Soldier of the Pantheon}
4 {Precinct Captain}
2 {Daring Skyjek}
1 {Dryad Militant}
2 {Brimaz, King of Oreskos}
3 {Mirran Crusader}
2 {Imposing Sovereign}
2 {Mother of Runes}
4 {Lingering Souls}
4 {Brave the Elements}
2 {Elspeth, Knight Errant}
3 {Honor of the Pure}
4 {Sword to Plowshares}
3 {Godless Shrine}
1 {Isolated Chapel}
1 {Temple of Silence}
1 {Windbrisk Heights}
17 {Plains}
Sideboard
2 {Rootborn Defenses}
1 {Gideon Jura}
2 {Renounce the Guilds}
2 {Rest in Peace}
1 {Thalia, Gaurdian of Thraben}
2 {Oblivion Ring}
1 {Nevermore
2 {Sin Collector}
1 {Return to the Ranks}
This is an old decklist and hasn't been updated much recently. It's also relatively on a budget, so no {Mutavault} or more kitty kings yet.
Here's an example of my old human based mono white deck with some new additions that I didn't know existed when I had it.
4 {Champion of the Parish}
4 {Soldier of the Pantheon}
4 {Elite Vangaurd}/{Boros Elite}
4 {Gather the Townsfolk}
2 {Elite Inquisitor}
2 {Mother of Runes}
4 {Silverblade Paladin}
4 {Mirran Crusader}
2 {Elspeth, Knight-Errant}
4 {Swords to Plowshares}
4 {Brave the Elements}
22 Plains
Here's a soldier tribal list off the top of my head.
4 {Soldier of the Pantheon}
4 {Dryad Militant}/{Elite Vangaurd}/{Boros Elite} (whichever you prefer}
4 {Precinct Captain}
4 {Raise the Alarm}
3 {Brimaz, King of Oreskos}
4 {Preeminent Captain}
2 {Honor of the Pure}
2 {Obelisk of Urd}
2 {Elspeth, Knight-Errant}
4 {Brave the Elements}
4 {Swords to Plowshares}
18 Plains
2 {Mutavault}
2 {Windbrisk Heights}
Some other budget options
Cut the nonbasic lands for plains.
{Archetype of Courage}
{Mirran Crusaders}, even though they are not soldiers
{Captain of the Watch}, other more expensive mana-wise soldier tribal (I focused this more on cheap creatures, low land count)
Mmm {Doomed Traveler} is a good option, but you need more enchantments, for example {Honor of the Pure}, {Crusade}... But your crearures is more smalls. You have prevent cards how {Engineered Plague}, {Mutilate}... This cards its Aquiles's talon for this mazes.
Sorry for my english.
