This fight is not terribly difficult, in and of itself. You'll want some way to keep your BB gauge up, you'll want some way to handle status ailments (especially paralysis), and you'll want to do lots and lots of damage. People trip on this fight by bringing awesome units that are hampered by their summoning arts, and then wonder why they never get to use their 7* unit's abilities and consequently die.
