Jumpluff

Jumpluff's access to Sleep Powder plus Infiltrator lets it temporarily incapacitate a Pokemon even when behind a Substitute and goes well with its very good Speed tier, which lets it outspeed Scyther and Pyroar while Speed tying with Archeops and Tauros. Other moves such as Memento and U-turn make it a great team supporter, letting Pokemon set up with more ease in the former's case and letting it keep up offensive momentum in the latter's case. Jumpluff also sports decent typing that gives it good STAB moves and nice resistances to Water, Fighting, and Grass. However, Jumpluff's pitiful Attack stat means it often can be taken advantage of and relegates it to strictly a support role, as it's otherwise outclassed by other Grass-types such as Shiftry and Lilligant. Additionally, its average defensive stats and weakness to Stealth Rock make it difficult for Jumpluff to switch in safely and utilize its resistances as well as it would like.
