Wuthering Waves: Peaks of Prestige TCG Mysterious Challenger - Calcharo

Calcharo is the final boss for the Mysterious Challengers. The overall goal is to prevent him from summoning Hecate early on in the game. You 100% want Feilian Beringal + Cantarella because of Hecate. The goal is to summon your Carapace as early as possible and tank the rounds for as long as you can. You want to delay Hecate's summoning long enough to buff up your Carapaces. Feilian Bringal will help your Carapace tank Hecate better, and essentially you will have enough damage to beat it. I didn't use Hoartoise, but it will greatly help you to tank the rounds more easily as well.
