I actually quite like this, especially in decks that can leverage that high power token into Greater Good, or Gitrog, Ravenous Ride
I've played persist combo before, so while it was nice to have my deck just happen to give me everything I needed, I know full well that the real fun comes when you have to deal with adversity
Whenever he is in attack position, simply use his effect, turn him to defense, and then Special Summon 2 Ninjas from your Graveyard with no strings attached
But they probably also just Thawed ten or so Islands out
I can see it used in limited
We did test out Gray Viking Games and verified that the codes we bought there worked
