If you happen to own one of these cards and want to sell instead, AncestralMTG is your best bet, since they specialize in valuable Magic oddities

Oddly, the green/black Invasion of Lorwyn doesnt interact with incubating at all, making it something of a dead card in your deck outside of some one-off removal
Players will want to take advantage of all the various forms of removal in the Emerald and Ruby starter deck, from returning Characters to a players hand through Cruella de Vil, Miserable as Usual, and Action cards like Dragon Fire
5 cards of rarity rare or higher
But regardless of all that, I still found your graph to very interesting and cool:) This is correct
