Oh wow, Na'Not'k is probably the best killer shapers have ever gotten. It's always going to have a base strength of 2, which in the vast majority of situations is good enough.
Jinteki gets garbage. Rover is not great. God of War looks like a perfect backup breaker for a tag-me deck.
Flashbang is INTERESTING, but how many sentries of cost 6+ are corps playing? I don't think it's going to make a splash right now, maybe if people start playing more expensive sentries.
Helheim could be really useful for scoring behind but that doesn't seem to be HB's game plan at the moment.
