Hello, I'm a Pokémon enthusiast with a deep knowledge of the franchise's lore and evolutions. When it comes to the evolution of Excadrill, it's a bit unique because it involves a special evolutionary stone that's not used by any other Pokémon.

Excadrill evolves from Drilbur when it is traded while holding a Douse Drive. The Douse Drive is one of the three Technical Machines (TMs) that are used in the Dream Radar game to evolve certain Pokémon. In the context of the main games, these TMs are not used for evolution but rather as items to trigger it.

Here's the step-by-step evolution process:


1. Drilbur is the first stage.
2. When traded and holding a Douse Drive, Drilbur evolves into Excadrill.

So, the evolution line is straightforward: Drilbur → Excadrill.
