Sphinx of the Guildpact lands as a 5/6 flying, hexproof, devoid defender that no targeted spell can touch — the cost is a clunky seven mana with five colors of pips that punish inconsistent mana bases. It's a legitimate threat in the right shell and a dead card in the wrong one.

Sphinx of the Guildpact is a Commander card through and through — the five-color pip cost is only manageable in a 100-card format where dedicated fixing is a deck-building category. In five-color Commander shells, it's a cheap finisher that dodges nearly all spot removal and blocks flyers cleanly. Competitively, it's too slow for Modern, Pioneer, or Legacy, where seven mana wins the game outright rather than deploying a single hexproof beater. Oathbreaker is theoretically legal but shares the same problem: the format's lower life totals and faster clocks mean Sphinx of the Guildpact rarely resolves in time to matter.

Price Context
Current price
$0.14 bulk tier
At $0.14, Sphinx of the Guildpact is pure bulk — you're paying for cardboard, not scarcity. The price reflects its narrow fit rather than power level; it does exactly what it says, but only in five-color Commander, which keeps demand low and the price firmly on the floor.
