Love this deck, and now, after the nerf, I think that will be more competitive (specially with balance). With the post-nerf i was able to defeat amazoness, spellbook, fur hire, geargia, archfiend and etc easier than I thought. Definitely a good deck :)
I think people would say Fur Hire is the most competitive deck right now (along with Spellbook).
I do think this deck is underrated though. You'd be very destruction resistant if you get Arms of Destiny with a Noble Knight. With Drystan, you'd even get a destruction effect.
The biggest problem is they're not resistant to banishing. You probably got lucky against SB, and Amazon can be a problem.
Against SB it's a coin game. If you go first with SB, do not let them having a spellcaster on the field and try to finish the duel as fast as you can. Now with the limitation of the Onslaught, NK can win more games against Amazoness, but still, it's a difficult matchup. But definitely a underrated deck and very, VERY Strong. (But expansive as 🔥).
