Critical Speed (Japanese: 技急所時素早さアップSpeed Boost When Move is a Critical Hit) is a family of skills in Pokémon Masters EX.
Effect
When a Pokémon with this skill lands a critical hit, it has a chance of raising the user's Speed by one stat rank. The skill can range from Critical Speed 1 to Critical Speed 9, with higher numbered skills resulting in a higher chance of activation. Critical Speed 9 will always raise the user's Speed. The skill applies to the Pokémon's usual attack moves, including buddy moves, but not sync moves or max moves.
The skill will only activate once per attack, so if the Pokémon lands critical hit against multiple targets, or gets multiple critical hits from a multistrike move, the skill only activates once. However, if the Pokémon has multiple instances of the skill, all instances activate simultaneously.
buddy moves, but not sync moves or 
max moves.
