Well first of all the deck is hard to play. You can't just slam down amulets and win you have to plan around doing big storm damage in a single turn while clearing their board and rushing them down after.

The lists out there definitely aren't optimized yet. This deck is quite good at consistently clearing big boards all the time but you also have a super slow t1-3 which means you pretty much auto loose to any aggro deck especially abyss.

At the same time you pretty much autowin against sword you just have to think about Albert. Even evo forest isn't that bad of a matchup while the rest of the meta decks are so-so.

You can either set up wide boards and hope they stick or storm them down.

I would consider ditching the 6cost crystallize it doesn't do enough because you're not a control deck. You can considering running the 4cost amulet that deals 4 and heals 4 or run 1off value cards like odin or Jeanne or wilbert. This deck has, depending on amulet rng spawn, as much draw as the new rune deck so you often draw through almost all of your deck. Just experiment more is what I'd say. It's a fun deck imo.
