A Mysterious CreatureHow it works & interactions with other cards

What It Does

A Mysterious Creature is not a playable spell in your deck, but a helper card. It represents a 2/2 colorless creature with no name and no creature types. Crucially, it highlights that any face-down creature cast with the disguise mechanic or put onto the battlefield with cloaking has the ward {2} ability. This means if an opponent targets your face-down creature, they must pay an extra {2} mana or their spell or ability will be countered.

How It Resolves Step by Step

When you cast a card like Nightdrinker Moroii for its disguise cost, you pay {3} and place it face down. At this point, the creature is a 2/2 with ward {2}. If an opponent attempts to target this face-down creature with a removal spell, the ward {2} ability triggers automatically. The opponent is then given the choice to pay {2} mana. If they cannot or choose not to pay, their spell is countered and removed from the stack. You can turn the creature face up at any time by paying its disguise cost, which does not use the stack and cannot be responded to.

Common Mistakes

A frequent error is assuming all face-down creatures have ward {2}. This reminder card specifically applies to creatures cast with disguise or cloaked; older mechanics like morph or manifest do not naturally grant ward. Another mistake is forgetting that ward is a triggered ability. If an opponent targets your face-down Dog Walker, the ward trigger goes on the stack. If you turn the creature face up in response, and the face-up version (like Dog Walker) does not have ward, the ward trigger still resolves because the creature had ward at the moment it was targeted.

When to Play It

You use this reminder card whenever you are playing with disguise or cloak mechanics. It should be placed on top of your face-down card to signal to all players that the creature has ward {2}. This prevents 'gotcha' moments where an opponent taps out to cast a spell, only to realize they cannot afford the ward cost. Once the creature is turned face up, such as turning a Nervous Gardener face up to find a land, the reminder card is removed.

Interaction examples

Searching and Protecting with Nervous Gardener

Nervous Gardener

You cast Nervous Gardener face down for {3}. It is now a 2/2 with ward {2}. If your opponent targets it with a spell, the ward ability triggers. After the ward resolves (or if they don't target it), you can pay {G} to turn it face up. This immediately triggers its ability to search for a basic land type, and the creature no longer has ward {2} because the face-up Nervous Gardener does not have that keyword.

Surprise Equipment with Concealed Weapon

Concealed Weapon

You cast Concealed Weapon face down as a 2/2 creature using its disguise ability. Because it was cast with disguise, it has ward {2}. Later, you pay {2}{R} to turn it face up. It ceases being a creature and becomes an Equipment. You then use its triggered ability to attach it to another creature you control, such as an Ornithopter, giving it +3/+0.

Defensive Maneuvers with Essence of Antiquity

Essence of AntiquityBoltbender

You have a face-down Essence of Antiquity and a face-down Boltbender on the battlefield. Both have ward {2}. Your opponent targets Boltbender with a destruction spell and pays the {2} for ward. In response, you turn Essence of Antiquity face up for {2}{W}. Its triggered ability gives all your creatures hexproof, making the opponent's spell illegal even though they already paid the ward cost.
