Emerald Charm 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

Choose one — • Untap target permanent. • Destroy target non-Aura enchantment. • Target creature loses flying until end of turn.

Complete guide

Emerald Charm is a versatile green instant that offers three distinct modes for just one mana. Whether you need to reset a utility land, clip the wings of a flying attacker, or remove a pesky enchantment, this card provides incredible utility for any green deck.

Choosing Your Path

As you cast Emerald Charm, you must choose one of its three modes: untapping a permanent, destroying a non-Aura enchantment, or removing flying from a creature. Because all three modes require a target, you must be able to choose a legal target for the specific mode you select before the spell can be cast.

Resolving the Charm

First, the spell is put onto the stack and targets are declared. Second, players have an opportunity to respond with spells or abilities. Finally, if the target is still legal, the chosen effect happens: a permanent becomes untapped, an enchantment is destroyed, or a creature loses its flying ability until the cleanup step of the current turn.

Understanding the Limitations

It is important to note that the second mode specifically targets 'non-Aura' enchantments. This means you cannot use Emerald Charm to destroy an Aura attached to a creature. Additionally, if you use the third mode to remove flying from a creature, that creature can still regain flying later in the turn if a new effect or ability grants it.

Strategic Timing

Emerald Charm is an Instant, making it an excellent defensive tool. You can untap a creature to create a surprise blocker or destroy an opponent's powerful global enchantment during their end step. Its low cost makes it easy to hold up mana while advancing your board state.

Interaction examples

Protecting Your Pieces

Heroic Intervention

If you target an opponent's enchantment with Emerald Charm and they respond by casting Heroic Intervention, their enchantment gains hexproof. When Emerald Charm tries to resolve, it will find its target is now illegal and the spell will be removed from the stack with no effect.

Setting Up Your Draw

Worldly Tutor

You can use the utility of Emerald Charm to untap a creature that has an activated ability requiring it to tap. This allows you to generate enough mana or a specific effect to cast Worldly Tutor immediately after, ensuring you find the creature you need before your next draw step.

Grounding the Skies

During your opponent's combat phase, they declare an attacker with flying. You cast Emerald Charm targeting that creature with the third mode. The creature loses flying, allowing your ground-based creatures to legally block it and potentially destroy it in combat.
