how to defeat esmeralda weapon

Deafeating emey takes alot of level, everyones final weapon and break, and the amount of materia you use. My dad said that emey uses a mover called arian transtorm, a mover that you'll take 1000 damage for each materia you have equipped. The best way to win is to remove most of your materia and use the master materia you get after you master every summon, magic, command, and the blue materia. Go to cosmo canyon after you do that and look at the huge materia, and you will get them. Also equip everyone with a mastered final attack phoenix combo(link them), give everyone a mime materia, give fastest character w-summon, equip mastered knights of the round linked to mp turbo, have w-summon person w-summon knights of the round twice, then mime them repeatedly. And if you die phoenix will be final attacked and revive all of your people! Try and let me know!

If you will try to google it you will find some sites that has walk through that can help you defeat esmeralda weapon.
