Looks like the Modern Horizons spoiler season has begun. I am not sure how best to evaluate this card. Obviously this does a great Force of Will impersonation which will be Modern legal and will probably see play there, but I am no expert on Modern. However, does it have applications in Vintage?
The fact that it's easier to hard-cast is something, but only being usable on your opponent's turn reduces the card to a purely defensive one. Then again, we've had decks in the past that have loaded up on Pitch counters beyond the 4 Force of Wills (such as Landstill) where this could see use.
Thoughts? This is definitely an interesting and clever printing by Wizards. Personally wish this didn't have the non-creature clause though...
