For me I'm using squad Full water unit, it help reduce damage from avant.

Using TRIDON, Selena, Lucina for defensive system

This is common mistake for last phase:

At turn 2 whent avant back to full hp you must use UBB

let him wipe your buff.

At 50% I don't reccomend you to use 75% mitigation

but SELENA UBB/ LUCINA UBB Instead

Spam your UBB but don't forget save hero crystal

for his ultimate attack, this time 75% + 50% mitigation

is reccomended.
