Despite their popularity, it's shocking to see that some of these Pokemon from the XY era didn't get a TCG card at all.

Mega Evolutions for Pokemon that don’t evolve will be playable as Basic Pokemon. This means a potential new Mega Rayquaza card would be playable without having to evolve it from its standard form.

With Mega Evolution and Pokémon Legends Z-A on the way, classic XY-era Mega Evolution cards are climbing fast. Here are 10 top picks to grab before prices go through the roof.

The new Pokemon Omega Ruby and Alpha Sapphire trailer below shows off Mega Rayquaza. Rayquaza, a dragon-and-flying-type Pokémon, joins Groudon and Kyogre to make up the twin games' three legendaries.

Rayquaza, a dragon-and-flying-type Pokémon, will be able to block moves such as Rain Dance, Sandstorm or Hail in its Mega form and more. For a look at Mega Rayquaza, check out the trailer above.
