Basically, filled with healing and divine shield cards, revolving as a midrange to controlling deck, as the Glass Knight is basically a repeatable removal spell. Thus, I included Howling Commanders to draw the Glass Knight(Or Bolvar), as it’s the basis of the deck, and Bolvar and Light’s Sorrow to revolve around the Knight’s divine shields. Faceless Manipulator, Spellbreaker, and Doomsayer run interference, allowing the Knight to stick around(Although Doomsayer CAN kill the Knight, so be careful), and Blessing of Kings and Consecration are just value.
Anyway, have fun with the deck! Maybe it isn’t particularly good, but maybe it is. Who knows.
