Cassius - Pros and Cons
Increases Hand Cycling
Cassius has many Cards that let him draw, allowing him to increase his hand cycling rate.
Build a Consistent Deck
By using his draw and card swapping abilities, you can build a stable deck that is less prone to a Bad Opening Hand. Since he often consumes AP, he has good synergy with Combatants that have AP recovery Cards.
Difficult to Use
Cassius is a Combatant that is somewhat difficult to use, as playing him requires an understanding of Card composition and how to play the deck. To maximize his performance, you will need to carefully adjust your save data and deck construction.
Cassius - Recommended Team
Haru Attacker Team Comp
