Wonder gives all your creatures flying as long as it is in your graveyard and you control an Island. Commander decks that flood the board with creatures love turning the team evasive, especially in token or go-wide shells. Self-mill and discard strategies easily enable it, making it a quiet finisher that appears out of nowhere. Its synergy with graveyard-centric blue and Simic decks keeps it in circulation as a sneaky win condition.
