This is super cool and probably a good include for 5c EDH decks but I cannot see this actually played anywhere else. Standard 5c/ramp decks can just get more lands for 4cmc and actually affect the board. You’d need this in your starting hand and even then does it do that much?
Interestingly this enables a t1 [[Leyline Binding]] if you can drop it from your opener. The flavor!
