Ratings
Cassius — Overview
Cassius is a tactical support who manipulates card flow through Quests, a unique mechanic that rewards task completion with powerful reward cards. Once activated—often via Pop Eyed Popper—each Quest asks for specific card plays (like using three 0-cost cards). Completing a Quest grants a potent reward and begins a new one. Cassius also boasts universal card searching, excellent draw tools, and strong defensive potential via his Ego Skill. While some RNG is involved, his adaptability is unmatched.
Strengths

- Unique Quest mechanic rewards diverse play.
- Great draw and cycling tools.
- Strong defensive Ego Skill.
Weaknesses
- RNG in Quest rewards.
- Buffs/debuffs are short and costly.
- Expensive Ego Skill.
