Carte Magic Duplicity

Duplicity 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.

01

Official card text

When this enchantment enters, exile the top five cards of your library face down. At the beginning of your upkeep, you may exile all cards from your hand face down. If you do, put all other cards you own exiled with this enchantment into your hand. At the beginning of your end step, discard a card. When you lose control of this enchantment, put all cards exiled with this enchantment into their owner's graveyard.

Complete guide

Duplicity is a fascinating blue enchantment that allows you to manage two separate hands of cards throughout the game. By exiling cards face down, you can shield your resources from discard effects or save a perfect combo for the right moment. Mastering this card requires careful planning and a good memory, as your hidden cards remain a mystery to everyone but you.

Dual Hands and Upkeep Swaps

When Duplicity enters the battlefield, you immediately exile the top five cards of your library face down. These cards form a secondary 'hand' that sits in the exile zone. At the beginning of each of your upkeeps, you have the option to swap: you exile your entire current hand face down and bring all the previously exiled cards back into your hand. Note that you cannot look at the face-down cards in exile, even those you just put there, so you must remember what you stashed away.

Maintaining the Balance

Duplicity comes with a price for its utility: at the beginning of your end step, you must discard a card. This represents the mental strain of maintaining two sets of thoughts. Furthermore, if you lose control of the enchantment—whether it is destroyed, exiled, or stolen by an opponent—all cards currently exiled with it are immediately sent to their owner's graveyard. This makes it a high-risk, high-reward engine for card selection.

Strategic Implementation

The best time to play Duplicity is when your current hand is weak or when you are facing heavy hand disruption. By swapping your hand during your upkeep, you can hide valuable spells from 'target player discards' effects. It is also an excellent tool for combo decks that need to assemble specific pieces without telegraphing their plan, provided you can protect the enchantment from removal.

Interaction examples

Generating Extra Value

With Kindred Discovery on the battlefield naming a creature type, every time you play a creature, you draw cards into your current hand. During your upkeep, you can use Duplicity to swap that large hand into exile for safe keeping, then bring back your original five cards to continue your development. This protects your massive hand from being discarded during your end step or by opponent spells.

Aggressive Card Draw Cycles

If you attack and deal damage with creatures while Bident of Thassa is out, you draw cards. Because Duplicity forces a discard at the end of your turn, you can use the upkeep swap to rotate between a 'drawing' hand and a 'casting' hand. You draw into your active hand, then at the start of your next turn, you swap those new cards into exile to protect them while you play the cards you previously hid.

The Risk of Duplication

If you use Trickster's Talisman to copy a creature that has an 'enters the battlefield' trigger related to Duplicity, or if you somehow copy the enchantment itself, remember that each Duplicity tracks its own set of exiled cards. If you lose control of one specific Duplicity, only the cards exiled by that specific instance will be put into the graveyard. If the token created by Trickster's Talisman is a copy of a creature that somehow grants control of Duplicity to someone else, the original controller will lose all their exiled cards.

How it works : Duplicity

Original English text — Wizards of the Coast / Scryfall

  1. #1· Wizards of the Coast

    For a time the last ability triggered when Duplicity left the battlefield. It has been restored to triggering when you lose control of Duplicity.

  2. #2· Wizards of the Coast

    Taking control of another player’s Duplicity will trigger the ability that causes the cards they exiled to be put into their owner’s graveyard.

    No other card is named in this ruling.

  3. #3· Wizards of the Coast

    The cards are face down all the time. You can’t look at them. This applies even to cards from your hand that got swapped out. You have to remember what they were if you care.

    No other card is named in this ruling.
