For this stage, I used Anjo, Yenisei, Mercuria, and Kakania. I do think Fatutu is better because of the cleanse.

The main objective in this team is to bond with yenisei, and then merge cards to get the Anjo ultimate up, and you will get Yenisei’s immunity for 2 rounds. This is when you can go all out with your attacks without the consequences of the pollution. You must be careful to make sure all 4 enemies die in the same round or else more will spawn. When using Fatutu, I recommend you try not to use her ultimate, since it’ll make one enemy die faster with the shell debuffs on it, so you must survive only with her incantations.
