This is not your common Knight Aggro Deck, but more like a versatile Aggro/Control. You have tons of good and cheap creatures with creature and enchantment removals.
The main card of this deck is Haakon, Stromgald Scourge. If you discard it unless he is removed from the game he let you play from graveyard all knight cards, including
Nameless Inversion
. If you don't care about deck Format you can use Buried Alive instead of
Funeral Charm
Many people ask me "Why Orzhov Basilica? It sucks!". Well actually it is another "discarder" for Haakon for early phases: let's say you start your first turn drawing a card and putting a land, now you have 7 cards in hand. When is your second turn you draw the card and play the Orzhov Basilica leaving you with an hand of 8 cards and make you discard one, Haakon.
Funeral Charm
can be used to discard your own Haakon in order to summon it or to buff your own creature making your knight more terribile threats.
Mirran Crusader and Phyrexian Crusader got almost every protections except blue making them hard to deal for a non-blue deck.
Knight of the White Orchid
works great with Orzhov Basilica and Path to Exile. Remember it allow you to play Godless Shrine because it's a plain card.
Knight of Meadowgrain are cheap, strong fighters and give you lifelink making you more resilient to damages in the early phases.
You finishers are either
Mirror Entity
and/or Kinsbaile Cavalier making your knights stronger and with both of them something like be able to kill 2-3 players in terms of damages.
Vault of the Archangel costs a bit but makes you able to attack without care about anything because you'll kill almost any creature which block you (first strike + deathtouch=ouch!) and let you earn a lot of life.
Tips
If Haakon or another knight is going to be removed from game, you may choose di kill him instead with a
Nameless Inversion
. You don't need to worry about been buffed by Knight Exemplar because Nameless Inversion remove creature type so they lost all buffs.
Against burn decks you'll need your side because they may burn you faster then your lifegain from lifelink creatures.
