Mega Blastoise is the Mega Evolution of Blastoise, a Water-type Pokémon. Mega Evolving keeps its Water typing while it sharply raises its stats for the duration of a battle.
“The rocket cannons on its shell fire jets of water capable of punching holes through thick steel.”
Mega Evolution debuted in Pokémon X & Y (2013) as a temporary, in-battle transformation. In the Pokémon TCG it appears first as “M” Pokémon-EX cards in the XY era, and again as Mega Blastoise ex cards in the Scarlet & Violet "Mega Evolution" era — both of which are among the most chased pulls of their sets.
Chase Season tracks 4 Mega Blastoise cards across 3 sets, with daily market prices and Chase Index rankings. The most valuable right now is M Blastoise-EX from Evolutions at around $57.86.
