Attacks

Bind20
Flip a coin. If heads, the Defending Pokémon is now Paralyzed.
Tunneling
If your opponent has any Benched Pokémon, choose up to 2 of them. This attack does 20 damage to each of them. (Don't apply Weakness and Resistance for Benched Pokémon.) Brock's Onix can't attack during your next turn.

Artwork Description

The artwork on this card depicts Onix burrowing through a dark, rocky tunnel, emitting glowing green energy that illuminates its rugged, segmented body as it tunnels forward with focused determination and strength.

Playability Overview

Brock's Onix has decent HP and useful status and multi-target attacks but is hindered by its high retreat cost and inability to attack after Tunneling, limiting competitive viability.

Binder Inspiration

Main Binder Theme: Rock SolidPlace Brock's Onix in the center of a rocky terrain-themed page. Its earthy vibes work well as a strong anchor, surrounded by other Rock-type Pokémon or those with a similar rugged aesthetic. Use cards with earthy colors to complement its look.Additional Binder Suggestions: Mountain / Sturdy / Earthy Brown / Rocky Terrain / Gym Leaders
