Last year was devastating to Magic: The Gathering in terms of card bannings and potentially high losses for card investors
Its not uncommon for players to ramp to extraordinary amounts of mana and scrap a win together via a snowball of several spells in one turn
Really I just see this as a combo piece and so it is somewhat narrow, it is not even that powerful compared to many of the possible targets, and certainly not for its mana cost, it is just so highly convenient for combo
Pillar Analysis: This card perfectly embodies Scarcity (Alpha set, ~1,100 printed), Legendary Power (the most broken artifact ever), Iconic Art/History (by Christopher Rush), and Pristine Condition (a perfect CGC 10 grade)
