Knights are a heavily supported creature type concentrated in white, black, and red. Knight decks commonly combine efficient attackers, combat abilities such as first strike, and typal bonuses that turn a collection of armored creatures into a disciplined army.
Haakon, Stromgald Scourge lets Knights be cast from your graveyard, while Worthy Knight creates Human tokens as more Knights are cast. Syr Gwyn, Hero of Ashvale adds Equipment and card draw to the typal strategy.
