The user's moves never miss. Negates recoil damage when using moves that have the Recoil effect tag.
Sure Hit & Recoil Removal (Japanese: 必中化&反動ダメージ無効Sure Hit & Recoil Damage Immunity) is a skill in Pokémon Masters EX.
Effect
In most circumstances, the user's moves cannot miss, regardless of the move's accuracy, the user's accuracy, or the opponent's evasiveness. However, the user's moves can still fail if the target is semi-invulnerable due to flying, bouncing, taking on a phantom presence, or taking on a shadow presence. In addition, when the sync pair uses an attack move that has the recoil effect tag, such as Head Smash or Steel Beam, the user takes no damage from recoil.
