With the rest of the cycle resembling Boons with the number 3 theme, how is this not a Mana Leak/Miscalculation-variant? :)

Good point, the blue card was the one card out I didn't keep consistent with the "3" theme of the rest. But I really like this as a plain cycling card, so it may just have to be a "cycle-less card" that's replaced with something like what you describe, with the "3" theme completed. I'd simply move this card into a stand-alone counter spell slot without a cycle then.
