Lilligant

At first glance, it may seem as though Lilligant is just another outclassed Grass-type. However, due to her access to the coveted Quiver Dance, this is not the case. With Quiver Dance, Lilligant is transformed from a hopeful bud into a bursting flower that dishes out a whole boatload of pain. Sleep Powder makes Lilligant even better, with many setup opportunities arising once an opposing Pokemon is put to sleep. Her Special Attack and Speed are excellent, but unfortunately she has mediocre defenses and limited coverage that hold her back. Her mediocre defenses are mitigated somewhat by Sleep Powder removing the need to take a hit and her coverage issues can be resolved with the right support. While Lilligant is definitely not a standalone sweeper by any means, her bursting power is not to be underestimated.
