So the thing that made Spectral Duke was the ability to gain advantage while not having to pay a lot for it. During the early game this is essential especially against those decks. Being on the ride chain is a way to do it and also getting value attacks always is how you maintain that early advantage. Prioritize damage over everything except in the case where your opponents rearguard is something you can’t deal with. Try to make your opponent use as many cards from their hand as possible and as early as possible.
