You can check the card's official details on the Pokémon Card Database.
One unusual detail is its evolution requirement. Mega Gengar ex is a Stage 2 card that evolves directly from Haunter. Mega Evolution Pokémon ex can skip the regular Pokémon form in their evolution line, as explained in The Pokémon Company's Mega Evolution announcement.
What Does Shadowy Concealment Do?
Shadowy Concealment is Mega Gengar ex's Ability. It makes your opponent take one fewer Prize card when one of your Darkness-type Pokémon is Knocked Out by damage from an attack by their Pokémon ex.
However, the Ability has specific conditions:
- The Knocked Out Pokémon must be a Darkness-type Pokémon.
- The Knockout must result from attack damage.
- The opponent's attacking Pokémon must be a Pokémon ex.
- Multiple copies of Shadowy Concealment do not stack.
This Ability is particularly relevant because Mega Evolution Pokémon ex give up three Prize cards when Knocked Out. If an opponent's Pokémon ex Knocks Out Mega Gengar ex with attack damage, Shadowy Concealment reduces that Prize-card reward from three to two.
How Much Damage Does Void Gale Deal?
Void Gale is Mega Gengar ex's only attack. It costs two Darkness Energy and deals 230 damage.
After dealing damage, the attack lets you move one Energy from Mega Gengar ex to one of your Benched Pokémon.
This extra effect can help prepare another Pokémon for an attack. Instead of simply losing the Energy used to power Mega Gengar ex, you can move one Energy to a Pokémon waiting on your Bench.

The Mega Gengar ex #284/217 Special Illustration Rare from Ascended Heroes is the standout collector's version among these English printings.

Before buying, check the card number carefully. A listing that only says "Mega Gengar ex" may not identify which version the seller is offering.
Is Mega Gengar ex Good for Pokémon TCG Battles?
Mega Gengar ex has two notable features: its 350 HP and its ability to reduce the Prize-card reward when an opponent's Pokémon ex Knocks Out one of your Darkness Pokémon with attack damage.
Its 230-damage Void Gale attack also moves one Energy to a Benched Pokémon, giving the attack an additional strategic effect.
However, it has limitations. Its Fighting-type weakness can make it vulnerable to certain attackers, and Shadowy Concealment does not work against every type of Knockout. It also requires two Darkness Energy to use Void Gale.
Whether it belongs in a competitive deck depends on the rest of the deck and the matchups it needs to handle. Its card text alone does not prove that it is a top-tier tournament choice.
Should You Buy or Collect Mega Gengar ex?
Mega Gengar ex offers different options for players and collectors. The regular Double Rare cards are relatively inexpensive ways to own the card, while the Mega Attack Rare and Special Illustration Rare versions offer more distinctive artwork.
For collectors, #284/217 is the standout version to compare. For players, the card's Ability, attack cost, and place in a deck matter more than its rarity.
Always check the card number, condition, and latest market price before buying.
