ya theres a mountain of things going wrong in this list, mainly that its got cards working against the theme, such as nova doomsayer and sheep in a mostly minion heavy deck. emperor isnt accomplishing anything fancy here it looks like your starting off as a freeze mage then playing into mid range cards, kel thuzad doesnt look like he is getting much value either.

Try not to disenchant cards your not using. you might need them in the future. while you said you have malygos and hes rarely played in anything useful he is a viable deck option at high level play if you build around him. just dont shard all your cards to make something then hate it and be in an endless loop of sharding cards for no value. if you have 2 of a card then open a gold one i suggest sharding the gold one though (since you already have 2 regular*) and that will help you expand your collection


Legendary cards you should shard are tinkmaster overspark, lorewalker cho, , gruul, i dont think anyone forsees them being anything close to worth having anytime soon.
