Due to Chain Lightning only having two previous printings, the paper price has crept towards $15 as this powerful card has been disappearing into many different Magic the Gathering collections. While being printed at uncommon will keep the price of the original versions from tanking, it's very likely that the foil version from Eternal Masters will be preferable to that of the Premium Deck.
Even being printed at uncommon in this set does not change its status in the popular Pauper format on Magic Online. It actually sees about the same amount of play in Pauper as it does in Legacy. It's good to see more copies of this classic burn spell printed outside of Magic Online.
