Your liability is probably in the billions at this point
But aggro decks with burn spells can easily turn this creature into a huge threat for just 2 mana
Dont get me wrong, hes a rad Commander that has plenty of potential, but he doesnt seem more in demand than many other cards from this year, on his face
Its expensive at seven mana, and honestly feels designed to be cycled away before using recursion to power it out down the road
Since this is an attack trigger, you dont need to have Narset live long or even through combat, you just need that hexproof to keep her safe until your next combat set
Furthermore, assuming the trend holds, this card's Japanese version is a safer bet to maintain its value than its counterpart in Prismatic Evolutions
