Looking for an angel to help a beginner

For Chapter 1 of the Space arc, characters with the 'Star-Resistant' attribute are key. Treasure collection is crucial, so make sure to grab it all. If you need any help, just ask, hmm!

Could you show me your deck, please?

Barrier Breaker + Warp Immunity + Alien Counter. Best characters: Pixies units.

For the space arc, you have to keep changing your deck due to sortie restrictions each time, so a general-purpose deck is meaningless. Collect treasures diligently, check the enemy composition, and bring the right units. Take them with you.
