Mass Polymorph exiles every creature on the battlefield and replaces them with an equal number of creatures flipped from the top of each owner's library — six mana for a potential board wipe that simultaneously cheats your best threats into play. The cost is real: six mana at sorcery speed means you're telegraphing the play, but the ceiling of converting token generators into Eldrazi titans makes it one of the most explosive finishers in blue.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

| commander | legal |

| modern | legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Mass Polymorph is a Commander card through and through — the format's singleton construction and multiplayer dynamics mean your opponents' creatures become variance weapons against them while you've engineered your deck to flip exactly what you want. Outside Commander, it's legal in Legacy, Vintage, and Modern, but six-mana sorceries don't compete in those formats' faster, more interactive environments. In Oathbreaker the tighter 60-card construction makes the flip more predictable, which is a mild upside. Mass Polymorph's real home stays at the 100-card table, where the combination of token swarms, tutor-to-top setups, and reduced interaction on sorcery speed gives it the room it needs to function.

Price Context
Current price
$0.32 bulk tier
At $0.32, Mass Polymorph is deep bulk — you're paying almost nothing for a card with genuine game-ending potential in the right shell. The price reflects its narrow build-around requirements rather than its power ceiling, so it holds value as a stable bulk rare rather than a card likely to spike.
