Formulas Used
Land Count: Land Count = Total Cards − 1 (Commander) − Non-Land Cards
Recommended Lands (Frank Karsten): Recommended Lands = 37 + (Average CMC − 3.0) × 3
Color Source Recommendation: Sources(Color) = round((Pips(Color) / Total Colored Pips) × Land Count × Multicolor Factor), where Multicolor Factor = 1 + (Color Count − 1) × 0.05
Pip Ratio: Pip Ratio(Color) = Pips(Color) / Total Colored Pips × 100%
Mana Base Deviation: Deviation = Actual Lands − Recommended Lands
Assumptions & References
- Commander format uses exactly 100-card singleton decks (1 Commander + 99 cards), per official Commander rules.
- Land recommendations are based on Frank Karsten's mana base research (How Many Lands Do You Need in Your Deck?, Channel Fireball), adapted for 100-card Commander decks.
