I ran into that when I was listing the deck archetypes for each player. And at first I wanted to list it as Gush because it plays Gush and operates with the Gush "rules" and that's the easiest way to classify it quickly. But I agree the mindset of playing the deck is more like Combo. But I believe the main archetype and the sub archetype are sort of interchangeable for this deck. You could call it Gush Combo or call it Combo Gush. The metagame breakdown takes into account the first word.
