Darkness
+20Gengar EX from Genetic Apex has been the butt of all jokes since time immemorial. Despite banning Supporters from coming into play, it never kicked off, and the community speculated that the eventual Mega Gengar would be the saving grace for fans of the purple ghost.
Enter Mega Gengar EX, a Darkness type instead of Gengar EX’s Psychic typing, and taking the shenanigans to another step by preventing all Trainers from being used.
The problem? It’s Stage 2 and needs 4x Energies to attack. With the Darkness type having no Pokémon to ramp Energy, it’s highly likely that by the time Mega Gengar EX is live, your opponent would have used almost all of their Trainers.
If you’re high on using 4x Dark EX cards, there’s Guzzlord EX, which is stronger with an additional 2x Energy attack (alongside the possibility to eliminate the opponent’s Energies) and is less risky as well. It’s also easily switchable via Celesteela, so there’s that to compensate for its high retreat cost.
So technically, Mega Gengar EX is poorer than Mega Charizard EX, and it only works in odd situations where you get it kicking quickly, and Chingling is there as a buddy.
Besides, even if you keep Guzzlord EX aside, the Darkness meta is brimming with meta-relevant Pokémon like the classic Darkrai EX, Mega Absol EX, Nihilego, and the new Darkrai from Mega Shine.
Mega Gengar EX will be forgotten by the next set, which is a major expansion by the way (B3).
