While specific builds vary by character, some Skill Cards are universally useful. MP Recovery (Small/Medium/Large) cards are essential for maintaining skill usage throughout a battle. HP Recovery (Small/Medium/Large) cards provide crucial survivability. Attack Boost and Defense Boost offer general stat increases that benefit any character. For offensive players, Chain Power Up (Puyo) and T-Spin Bonus (Tetris) are highly effective. Defensive consider Garbage Shield or Status Effect Resistance. Always aim for a balanced set of cards that support both offense and defense, and consider cards that synergize with your chosen character's innate abilities.
