Venomoth

Venomoth's Speed advantage over other common leads combined with Sleep Powder makes it easy for it to provide early-game support. After neutralizing a foe, Venomoth can easily make use of Baton Pass and Substitute to freely get a teammate into an advantageous position. Furthermore, despite Venomoth's uninspiring damage output, Baton Pass helps it keep momentum up against possible switch-ins like Metang and Sableye. Unfortunately, Venomoth is rather limited beyond these options, and its fragility makes it a poor check to Pokemon like Hitmonchan and Arbok that it'd like to switch into. Venomoth also has no means of boosting its stats apart from Silver Wind and Berries and has to use its much lower Attack stat if it wants to make use of its STAB moves. Despite these faults, Venomoth makes for a capable lead and team player on offensively inclined teams that are looking for something a little different.
