yes that team is fine.

seal eva and keep her sealed. you don't want her using mess on you. kill of mobs in this order;
earth -> fire -> wind. when a waters spawns, leave them, do not kill them.

when only water are left kill eva while still keeping her sealed. when she's dead then you can kill the waters and any thing else that spawns after, do them one at a time.

reason why i say to kill in that order is cause of seals. also the water are stupid they only heal. if they manage to seal you it only last for two turns so not impportant.
