First, dont build this deck.
Second, if you build this deck.
Striking snake with wurm stone will summon the wurm and give it killer.
Thrashing dune wurm is nice to buff your whole board with striking snake
Unraveling fanatic is actually performing much better than I expected. The card draw is not the same as nightfall you get the draw first so unless your opponent removes it right away its becomes a 3 cost draw two. Card can finish games with Alhed on board. Also if he survives 3 turns and transforms into sanitys antithema it combos with wurmcalling.
Pit is nice
This should probably be a crown deck somehow since I begrudgingly had to add primal to get all the worms, and it has lots of draw. I dont know how to piece that together and still maintain the theme though.
If you are still here, and have ideas throw um at me please.
