This is my version of White Knights. I essentially approach it as a combo deck, with the combo being two copies of Knight Exemplar in order to make your whole board indestructable (and then laugh in the face of board sweepers). To that end, the deck runs four copies of Phyrexian Metamorph, which are essentially Knight Exemplar 5-8. There is no source of blue mana in the deck, so casting them does cost 2 life, however it is absolutely worth the cost.
Knights tribal gives us access to a host of creatures with useful combat abilities:
1 drops:
Student of Warfare is the only 1-drop knight worth running. It's a fantastic card that converts unused mana into a creature that becomes very scary, very fast. A useful 1-drop and a great topdeck as well. Helps the deck to deal with flooding.
2 drops:
Knight of Meadowgrain is just nuts. The first strike/lifelink combo is very powerful and makes it near impossible for an opponent to race this deck if they can't remove it.
Leonin Skyhunter is pretty vanilla, but there aren't many choices when it comes to knights with flying. The Skyhunter is cheap, efficient, and gives the deck needed evasion.
Knight of the White Orchid is a fantastic mana accelerant. Played properly he allows you to put out two 2-drops on the third turn. He also allows the deck to keep the land count low.
3 drops:
Mirran Crusader is a modern staple. His protections make Abzan players unhappy and Abzan is everywhere.
Support Cards:
Path to Exile requires no introduction.
Brave the Elements is the best reason to play mono-white. It gives the whole team evasion to force through damage. It counters spot removal aimed at your Knight Exemplar. It blanks damage based sweepers. It's a 1-drop. It's an instant. It's OP.
Honor of the Pure makes our weenies relevant in the mid to late game.
Manabase:
Plains, they tap for W, which is useful.
Flagstones of Trokair provides deck thinning without all that pesky paying of life required by fetch lands.
Cavern of Souls hoses control. An uncounterable Knight Exemplar is a beautiful thing.
Horizon Canopy is here solely to hedge against flooding.
Windbrisk Heights grants conditional card advantage and card filtering. The deck runs more than enough creatures to trigger it.
