【FGO】Saber Gilles immortal Castoria Team
actually pretty decent, you can use him as a Reines substitute, the way it work is basically spam tamamo np as much as you can, with 2 tamamo np you can get gilles 1st skills back before the next castoria np. if you cannot achieve that you can use castoria 3rd skills and atlas as a backup.
You can use Merlin instead of tamamo, a bit more risky but bigger damage.
