Marauding Sphinx

Marauding Sphinx is legal across every major constructed format but sees essentially no play outside Commander — five mana for a 5/5 flyer with a conditional draw effect doesn't clear the bar in Legacy, Modern, or Pioneer, where the game is often over before it matters. In Commander, the math changes: four opponents means more chances to hit artifacts on the reveal, and a 5/5 with flying is a credible threat on a board where Wrath effects reset the battlefield. It slots most naturally into artifact-matters decks or political builds that benefit from watching opponents' hands cycle. Oathbreaker is the only other format where it might find a home, and only in a shell built to exploit the trigger.
