Each pair of bars is the deck as sold (gray) and the upgraded deck (blue). The curve and the average cover Lathliss, Dragon Queen and every nonland card. Game Changers are the cards on the official Commander Game Changers list. Combos are the two- to four-card combos from Commander Spellbook that the 100 cards hold every piece of. Deck match says how much of what this commander’s decks usually play the list captures.
