Quote from Ratwohl »But in a situation with five atrifacts, shouldn't you be ahead on mana anyway?
That's pretty much been the conclusion in the Legacy scene since the card was spoiled. Actual Tolarian Academy? Busto. Academy that costs 4 mana to play and flips when you already have stuff going on? Not super great. The power of the flip cards outside of standard is directly tied to how much mana they cost to get down in the first place, and what effects they have for that cost. Flipping needs to be a value-add, not the reason for playing it.
