Even if it does pull its weight in the prowess deck, I’d argue that it’s not worth it (my point of view of course). I’ll explain my take.
A while back I made a lower powered version of my cube to contrast with my friend’s powered cube. The synergy was great with many overlapping glue cards and archetypes. But you know what? It wasn’t as good as I had hoped because a bunch of the cards just weren’t exciting to draft or play! Sure they fit the decks and archetypes just right, but that helped me realize that you’ve got to give your drafters something to work with!
Nobody really wants to cast a 3/1 for 3 if they don’t have to (again, my very subjective point of view). I’d rather find a more exciting card that can have applications in the prowess deck (even if not as explicitly supporting the deck).
