Now that legendaries can only be opened once so long as you own a copy of the card, you should never disenchant legendaries until you get duplicates of them (after you already have all the legendaries in an expansion). Think about it: if you disenchant Lanathel right now, you're only getting 400 dust in exchange for creating the chance to simply open her again in a pack as opposed to a legendary you might actually want. In the long run, it will be best for you to keep legendaries you don't have a use for.

Not to mention, I wouldn't be surprised if the discard mechanic gets further support in the next expansion, even though I think most players hate the mechanic.

Great deck! I love control decks, and I hate running whatever the flavor of the month net deck is, and so this fit my niche. It's the only deck I've been able to consistently win with outside the Tempostorm tier 1 rankings :)
