The moveset leans on Electric and Dark coverage to catch would-be counters. Chartiberry means extra utility for Grubbin, and spread EVs make sure nothing walls it cleanly. Swarm fills in the gaps.

TMs carry this one. Grubbin learns X-Scissor and Lunge naturally for STAB, but the offensive range comes almost entirely from technical machines. Ground and Normal and beyond give it real matchup play.
