As a Sphinx with six mana value, it commands a {4}{U}{U} mana cost and brings a 4/4 power and toughness to the battlefield.

The card’s design centers on a strategic advantage that rewards Sphinx-based decks. Flying allows it to evade most blockers, while its static ability reduces the casting cost of other Sphinx spells by {2}. This synergy makes it a valuable engine piece for players building decks around the Sphinx subtype. The creature’s triggered ability adds another layer of depth: whenever Unesh or another Sphinx you control enters the battlefield, you reveal the top four cards of your library. An opponent then splits those cards into two piles, allowing you to choose one pile for your hand and the other for your graveyard. This mechanic provides card selection and resource management, blending luck with opponent interaction.
