- AI reports that explain the numbers — From quick primers to full deck analyses, mana audits and coaching, AI turns every simulation into readable strategy — game plan, weak spots, what to change.
- The tournament meta, built in — Fresh staples, inclusion rates and top-performing decks from real tournament results sit right next to your list, so you build against what's actually winning.
