Mega Steelix is the Mega Evolution of Steelix, a Steel/Ground-type Pokémon. Mega Evolving keeps its Steel/Ground typing while it sharply raises its stats for the duration of a battle.
“This Pokémon evolved through use of a strange item. Its body is coated with steel powder and notably hard—not even diamond can leave so much as a scratch.”
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 Steelix ex cards in the Scarlet & Violet "Mega Evolution" era — both of which are among the most chased pulls of their sets.
Chase Season tracks 2 Mega Steelix cards across 1 set, with daily market prices and Chase Index rankings. The most valuable right now is M Steelix-EX from Steam Siege at around $26.24.
