I seriously want to love this guy. His events are excellent, and with only a little preparation you can reliably have a double resource card or wild resource available to feed them. (two of his events will double a wild resource used to pay for them, meaning they effectively only cost a single resource)
The problem is...most of his events are only good, not great.
Which leaves him in this weird limbo, where you basically build a deck around the additional cards, and Nova's just along for the ride. Not that there aren't effective decks with this approach, I was just hoping Nova would synergize more with existing cards.
That said, I have high hopes for him moving forward, as he has a tremendous amount of wild resources available, and I think this will prove very beneficial in the future.
