I don't believe such power should be granted by an item, but if it is worth noting I think the best form to balance it is to either turn it a single targeted spell (Such way you just copy a single champion's buff) or you think of something extreme, bring new CC to the game and purge surrounding enemy champion (You don't their buffs, but their passive or innate buffs are disabled, and their temporal buff cleansed from them).
