This battle can be easy as long as you bring your Casters. However, try to have a few other-class heavy hitters like Berserkers since Casters aren't inherently strong fighters.
This is more or less the same as the previous battle.
This is why you shouldn't bring an all-Caster team and call it a day: Jeanne is resistant to Casters' attacks and there's a Wyvern Rider.
However, if you kept/swapped a Berserker or Avenger, you can make your day easier.
Strategies and Recommended Servants
If you want to not use the Chaldea Combat Uniform Mystic Code, Heracles is a recommended Berserker, not only is he strong, but he can possibly outlast the first 2 waves even if the enemies get lucky and he can even be effective at the third wave. But be sure to have his max bond CE equipped.
Any Avengers, even Angra Mainyu will work well against Jeanne.
The infamous combo of Merlin + Jeanne d'Arc Alter is extremely effective for this, since Merlin can withstand the earlier waves and kept supporting the team, and his support will amplify Jeanne Alter's effectiveness against Jeanne.
This battle is best for farming Transistor G (though you can get a small amount of Vacuum Tubes too here), therefore have at least one of your Servants equipping the CE . Due to the strength of the enemy here, you may consider putting into one of your fighters here.
