Molten Man, Inferno Incarnate

Legendary Creature — Elemental Villain • Mana cost: {2}{R} • Marvel's Spider-Man • Uncommon

When Molten Man enters, search your library for a basic Mountain card, put it onto the battlefield tapped, then shuffle.
Molten Man gets +1/+1 for each Mountain you control.
When Molten Man leaves the battlefield, sacrifice a land.

Is this it? Is this the end of Spider-Man?
