I think this has plenty of Modern applications as well. I play Temur Monkey Grow, so I'm biased, since I know outside of UW Control, most other decks with blue won't need this. But it counters Phoenix triggers, Thing in the Ice flipping triggers, counters Jaces, Teferis, Lilianas, there are a few legendary creatures running around - Kalitas, Thalia... I think this will certainly see some play.
