Simple strategy to destroy Phoenix at Full Might!!- Surviving Rebirth Flame- FF7 Rebirth

First impromptu strategy to surviving Rebirth Flame insta kill attack and destroying Phoenix at Full Might difficulty using Aerith, Cloud and Tifa.
1. Start the fight with Aerith and build Limit gauge by staggering the smaller enemies with her new improved kit. Cast Pray often to keep the party in decent health. Also steal Limit gauge from Cloud and Tifa to cast Healing Light whenever you get below 50% health across the party.
2. Put elemental Ice on Cloud and use aerial combos to fill the pressure gauge on phoenix.
3. Equip Tifa with sync ice to combo Clouds Triple Slash with blizzard while pressuring
4. Equip magnify defense magic on Tifa. Once you Stagger Phoenix twice cast manaward on the whole party to easily tank his instakill Attack.
5. Finish the fight by using any remaining limits or sync attacks (I played it safe but I could had finished it sooner.)
The full game is going to be next level when it releases.
