Battle notes

Grass / Poison cancels or softens common single-type weaknesses such as Poison, Bug, Ground, which is why the combined chart matters more than either type alone.
Because dual types multiply both defensive matchups, Fire attacks (2x) is the most direct way to punish this combination under the modern Gen 6+ chart.
Avoid defaulting to Grass, Water, Electric attacks unless you have a specific reason; this typing resists or blocks those lines of play.
This exact typing exists in the current National Dex, so the matchup is useful for real Pokémon pages and team planning.
