\"Niborn\"

{2}{U}{R}{G}, {T}: Put a legacy counter on Niborn. Then exile up to X target nonland permanents, where X is the number of legacy counters on Niborn. For each permanent exiled this way, its controller reveals cards from the top of their library until they reveal a nonland permanent card. That player puts that card onto the battlefield, then shuffles the rest, including the exiled card, into their library.
