I want to make my own expedition team

Power without harmony is fragile. Warriors alone have their limits, so the principle is to balance tanks and damage dealers. Find a combination that embodies your own beliefs. Good luck.

Warrior types tend to come out well in gacha pulls, making it easy to build a deck, and they're also good for the Expedition content later on. I made my first deck all warriors, and my second deck a mix, and once they hit level 40, it was pretty manageable to run two teams.

Leveling up my castle is so tough lol

Ooh, that's a good idea.
