Filtered Sincerity

This one was quite difficult due to the cooldown. But! I'm here to share a special way to easily clear 'Filtered Sincerity'. 1. Draw 'Agent Star' from the rare summon. 2. In the 'Filtered Sincerity' stage, draw 'Blade Master Star', the evolved form of Agent Star. 3. Clear the stage. Beginners can do it too. Good luck! + To help more people see this (and for me to get more benefits), please like and comment so this post can become recommended.
