Duel cast + time magic Quick = 5 spells per character = 20 spells a turn. But one turn and no MP left means it can't be used consistantly
Flare Sword is still pretty effective against Omega Mk. II, and enough Dragon Powers along with Rapidfire and two Dragon Lances/Dragon's Whiskers work wonders against Neo Shinryu.

Besides the obvious Dualwield Spellblade/Rapidfire and Quick/Dualcast Flare/Mime, etc, Mix can be pretty darn broken too. But nothing in this game really compares to anything broken in FFVI (hello there Wind God Cyan/Gau).
