Keening ApparitionHow it works & interactions with other cards

What It Does

Keening Apparition is a 2/2 creature for one white and one generic mana. Its primary utility comes from its activated ability, which allows you to sacrifice the creature at any time you have priority to destroy a target enchantment. Because the ability does not require the creature to tap, it can be used the same turn it enters the battlefield, even if it has summoning sickness.

How It Resolves Step by Step

First, you must have priority to activate the ability. You choose a legal target enchantment on the battlefield and pay the cost by sacrificing Keening Apparition. The ability is then put onto the stack; note that once the cost is paid, the creature is in the graveyard and cannot be saved or targeted. When the ability resolves, the targeted enchantment is destroyed and moved to its owner's graveyard.

Common Mistakes

A common error is attempting to use the ability on cards that are not enchantments. While some cards like Esper Sentinel are artifacts, they are not enchantments, meaning Keening Apparition cannot target them. Additionally, remember that if the target enchantment becomes illegal (for example, if it is returned to the owner's hand in response), the ability will not resolve and will have no effect, but Keening Apparition remains sacrificed.

When to Play It

This card is best used as a defensive measure. You can cast it early to block aggressive creatures and then sacrifice it to destroy a powerful Aura or Global Enchantment later. It is an excellent sideboard choice against decks that rely heavily on enchantments for their strategy.

Interaction examples

Combat Sacrifice

If an opponent attacks you with a creature, you can block with Keening Apparition. After blockers are declared but before damage is dealt, you can sacrifice Keening Apparition to destroy an enchantment. This prevents the opponent's creature from dealing combat damage to you while still resolving the destruction effect.

Invalid Targets

Esper SentinelOrnithopter of Paradise

You cannot use Keening Apparition's ability to destroy Esper Sentinel or Ornithopter of Paradise. Even though they are non-land permanents, they lack the 'Enchantment' card type. You must identify a card that specifically says 'Enchantment' in its type line to use the ability.
