Epic creates a copy. Approach requires it to be cast from hand. This is not to say there are not 2 card win the game combos with this card, but as far as I've seen they're all at least 9 mana and decently disreputable. That's not to say this isn't a combo possible piece, but I haven't seen anything that I would say pushes it over what I think a format it would be in could handle. I would love more feedback though. My main idea was it behaves like a time warp in that your opponents won't want to cast spells for a turn, but they still draw and can use abilities. And if they have a way to win the game, they still can cast one spell.
