Our tier lists rank cards and relics from S (best) to F (worst) based on overall power level, versatility, and win-rate impact. Ratings are based on general performance — always consider your current deck and synergies when making picks.

The AI Build Planner lets you input your current deck and relics, then uses AI analysis to recommend the best card picks, identify your build archetype, flag synergies, and estimate win probability.
