Mewtwo X vs Mewtwo Y – Which Should You Pick?

Most people are gravitating towards Mega Mewtwo Y for this choice, as you’ll ultimately be getting one of the most formidable fighters in the entire game, provided you can win that battle. Mega Mewtwo Y beats Mega Mewtwo X where it matters most, and the psychic capabilities it has are second to none.

Mewtwo X isn’t weak by any means, but judging from Pokémon tips, polls, and picks online, Mega Mewtwo Y is the one to go for.

Now, if you’re in that fight, you’ll want to know the best Mega Mewtwo Y counters, naturally.

Mega Mewtwo Y is weak to Bug, Ghost, and Dark-type attacks, so bear that in mind. The best counters for Mega Mewtwo Y, according to the top battle sites in the business, are as follows:

• Necrozma – Dawn Wings
• Mega Tyranitar
• Shadow Tyranitar
• Mega Absol
• Mega Gengar
• Shadow Hydreigon
• Shadow Darrai
• Lunala
• Mega Houndoom
• Eternatus

So, nothing simple, unfortunately. But that should help you get started with these challenges.
