Enigma Thief

Prowl on a seven-mana Sphinx is a strange marriage. The keyword was born on cheap Rogues slipping through for a discount, a mechanic built around chip damage and tempo, and here it hangs off a fat flier that wants to be the payoff rather than the enabler. The two halves quietly feed one another. Prowl is an alternative casting cost paid from the hand, so some other Sphinx or Rogue has to connect first: land a hit with the small evasive attackers a deck like this already fields, and this drops from its printed to , turning a top-heavy bounce spell into a discounted tempo swing. The enters trigger is what the discount buys: a multiplayer-scaled Man-o'-War that resets one nonland permanent from each opponent at once, a bounce that only ever points outward at the tables it was designed for. That is the cohesion. The tribal attackers that earn the prowl cost are the same board the bounce is clearing a path for, stripping blockers and problem permanents before the next swing lands. Without those attackers it is a slow, expensive 5/5 flier with a one-time reset stapled on; with them, it arrives ahead of curve and tilts an already-favorable board further. The whole reason to run it over a plainer bounce-on-a-body is the sum: it asks for a deck committed to evasive Sphinx and Rogue aggression, not one splashing it for a single reset.
