[SET Colosal]

The key card of this deck is recycling horror with the hero ability so I'd maximize that card and let knight out cause you want those allies in the graveyard. You are also lacking more direct and efficient draw, I'd take out the tombstone and add more lambs or bad santa. Most new players tend to dislike Bad Santa cause of the double sharp but used in the right moment is the best draw card. Cultists is a great option too cause it will discard a horror in t4 which you can immediately revive with GB.
Add a couple of darkrat
