Definitely a great card, and worth playing. I thought about putting it in the list over CoCo, but if it was my first turn play I wouldn't be able to
flash Leonin Arbiter in until turn 3 which by then i could already have an Arbiter in or Thalia in to stop fetch lands.
So personally I don't think it would be a great fit for my deck, but it is still an amazing card, and great for quite a few other decks.
Thank you for the recommendation however
