You could just see it as a version of the card, and thats absolutely fine
Among passive MTG blue spells and enchantments alike, few generate value as effortlessly as this card
Force of Will is the poster child of early-game interaction in Legacy, and thats an easy four-of
This is a combination that quite a few commanders would be quite fond of
Since it's an instant, you simply pass your turn, wait until your opponent's upkeep, and then cast it, which is very close to getting an extra turn (the main difference is that your opponent will get to untap)
Obviously, the cards that are in development need to be proxied, but I was surprised to find out that R&D didn't get upcoming sets much sooner than the rest of the world did.
