I'm liking a certain combo I have on Cid on my current playthrough. That would be Hades+Added Effect alongside a Cut All Materia (the Cut All isn't linked, but the other two are). The Hades+Added Effect on a weapon has the ability to inflict every status ailment that the Hades summon does, but in a standard attack. Add a Cut All to that, and you get that effect with every enemy in a random battle.
Granted, that only matters if it actually hits, and even then, the status isn't guaranteed. When it does hit, however, it's tough for the enemy to recover.
