I would recommend removing the Fearsome Awakening in favor of two Disdainful Stroke. Extra control benefits a deck that doesn't have the typical ramp that jund or temur colors provide. Food for thought, otherwise, great deck!

Have you considered removing one of the Crux of Fate for even a single copy of Disdainful Stroke? In all of my own control decks I try to keep at least one mainboarded due to how many disrupts I have caused with the card. Otherwise, it may not be necessary due to your local meta.

Interesting dragon deck. Like the amount of control it has without needing to target.

Not sure if you have issues with rush decks but you might want to consider either Fiery Impulse or Wild Slash if they are presenting a problem. This recommendation is because these spells being 1 cost can help if you are trying to stretch your mana further and gives you another "instant" board control option. I am not sure if you need 4 languish since you main board 4 crux.

Best of luck with the deck.
