Playing the Overlord on three will put you at four lands that turn, and if you have another land drop on your fourth turn, you can cast another Overlord for the full five mana, as a creature this time, while further ramping you to six lands
Ramp, by necessity, is primarily made of lands and cards that help you find and/or play lands
If a card is good then lots of people want it, and so demand is high
This list might also change in the future with the set still releasing, so be sure to come back for updated prices sometime in the future
This scoring enables a Bracket 2 to Bracket 1 downgrade: if a deck has a soft score of 2, a popularity score under 1.0 (meaning most cards are jank or niche), and fewer than 3 stax pieces, the calculator recognizes it as a theme deck or jank build and downgrades it to Bracket 1
