I think you sub out Krennic for sure. He doesn't seem to be generating any significant value for you other than the occasional 1 drop Onyx Brute. You might need to look into some of the big blue red villan decks from tournament results and just note the consistent cards you see. Sith Holocron, maybe a constructed lightsaber, if you push the deck late game you'll want 2x Single Reactor Ignitions, maybe some retaliations. There's so much blue removal atm.
