Having the ability to exile two cards to play is good enough at 3 mana in Red, so the base card is fine, but with Freerunning you can really dig for something you need
If so it should sit at the top of this list however it is an incredibly tough card to evaluate so I will need to do some significant testing before I insert the Promised End into this list
As you are trying to ramp these are generally only good when you have a land heavy hand or you have already ramped to your upper CMC cap
Whether thats a Clue, Food, or Treasure, or Brudiclad, or Thopter Assembly, or Wurmcoil Engine once you Thop, you cant stop
Plus it sounds way cooler
The cards are exciting, the idea for the Illumineers Quest was innovative and appealing to a broad range of players/collectors, and extra touch went into this sets Trove to make it ultra themed to the set
