Simon Nielsen, champion of the MTG Pro Tour Amsterdam with his Nadu Bant deck, believes this overwhelmingly powerful strategy should be banned as soon as possible. “This deck is ridiculously strong, and I’m just happy I got to use it before it gets banned, which it surely will,” he said upon receiving his trophy on June 30.

The latest Pro Tour winner expects the ban hammer to fall imminently on the Simic-colored bird wizard. Nielsen jokingly added, “Do not invest.” Despite the champ’s warning, many cards have already spiked in price over the last few days in reaction to Nadu, Winged Wisdom’s rise in popularity. Key pieces to the deck’s combo, such as Shuko, have seen an unbelievable upsurge in price.
