I made this originally because I didn't want to play templar, but still liked the knights in general, then I had the thought of what if they were corrupted knights brought back from the dead using carrionette and raise dead. This is what I came up with.

The whole premise behind this is instead of requiring the threshold and mana to summon the higher cost minions, they get sent off to the graveyard to be brought back using either the spells raise dead or carrionette, or sites like boneyard or Orpheus crossing. Then later as the board is developed, they can be brought back using book of the dead and so on.

generic combo that can be done if you have certain things in hand.

Combo one: going first or second

Starting hand; Spells - seasoned sellsword, any other minion, Sites - boneyard, den of evil

turn 1: play den of evil, summon sellsword, discard minion.

Turn 2: play boneyard, summon back dead minion.
