Mass Polymorph is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
Exile all creatures you control, then reveal cards from the top of your library until you reveal that many creature cards. Put all creature cards revealed this way onto the battlefield, then shuffle the rest of the revealed cards into your library.
Complete guide
Mass Polymorph is a powerful blue sorcery that transforms your entire board into a fresh batch of creatures from your library. By exiling your current forces, you gamble on the hidden potential of your deck to bring forth a game-ending army. It is the ultimate tool for decks that want to swap small tokens for massive, high-impact threats.
A Total Transformation
When Mass Polymorph resolves, you exile every creature you currently control. You then count how many were exiled and begin revealing cards from the top of your library until you find that same number of creature cards. These new creatures are placed directly onto the battlefield, while all other revealed non-creature cards are shuffled back into your deck. Unlike similar effects, the original creatures do not return; they remain in exile for the rest of the game.
Simultaneous Resolution
All creatures revealed this way enter the battlefield at the exact same time. This is crucial for triggered abilities; if multiple creatures have 'enters' abilities, they will all see each other enter. These abilities don't go on the stack immediately; they wait until Mass Polymorph has finished resolving and the non-creature cards are shuffled back. Then, the active player puts their triggers on the stack in any order they choose.
Empty Libraries and Constraints
A common mistake is worrying about revealing more cards than are in your library. If you exile more creatures than you have creature cards left in your deck, you simply reveal your entire library, put every creature card found onto the battlefield, and then shuffle. You do not lose the game for being unable to find enough creatures, as you are revealing cards, not drawing them.
Strategic Timing
Since Mass Polymorph is a sorcery, you should use it when you have a board of expendable tokens or low-cost creatures and a library filled with heavy hitters. Because it exiles all creatures you control, it is also a way to 'save' your board state from certain theft effects, though the primary goal is always to cheat out high-mana-value creatures.
Interaction examples
Sea Gate Restoration // Sea Gate, RebornIf you use Mass Polymorph to bring out creatures that have abilities based on your hand size, having previously cast Sea Gate Restoration // Sea Gate, Reborn ensures those creatures enter with massive power and toughness. Since Sea Gate Restoration provides no maximum hand size, your new creatures won't be weakened by a discard phase later in the turn.
Raise the PalisadeIf your Mass Polymorph reveals a specific tribe of creatures, you can follow up with Raise the Palisade. By choosing the creature type that matches your new army, you can bounce every single one of your opponent's blockers back to their hand, allowing your newly summoned creatures to attack an empty board on the following turn.

How it works : Mass Polymorph
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
If the number of creatures you exile is greater than the number of creature cards remaining in your library, you'll wind up revealing your entire library, putting all creature cards revealed that way onto the battlefield, then shuffling your library.
No other card is named in this ruling.
- #2· Wizards of the Coast
Any abilities that trigger during the resolution of Mass Polymorph (such as a creature's "enters" ability) will wait to be put onto the stack until Mass Polymorph finishes resolving. The player whose turn it is will put all of their triggered abilities on the stack in any order, then each other player in turn order will do the same. (The last ability put on the stack will be the first one that resolves.)
