Emboar is the most obvious alternative to N here. She has a great fire nuke, and is easy to setup. Swanna is the obvious support, and the third can literally be anything as long as its somewhat useful. I threw Cryogonal in there for Haze because why not. Get some lucky Potion RNG and it's an easy win.
One interesting thing to note is that the enemy sync decreases your attack (a throwback to the old days, where enemy sync would debuff you completely). So, you can just use Hilda's trainer move a second time to replenish the attack stat.
