Roserade

Powerful STAB moves, potent coverage, and high versatility make Roserade RU's premier Spiker. Said versatility gives Roserade the means to potentially beat almost any entry hazard remover, including the best spinner in Mega Blastoise, and its offensive prowess forces many switches that further ease setting Spikes. Sludge Bomb and Technician-boosted Hidden Power can cover almost anything that could hope to take Leaf Storm, including Flying-types, Fire-types, and Steel-types; this makes Roserade a problem for frail, offensive teams and slow, bulky teams alike. A Grass / Poison typing gives Roserade the resistances to switch into Water-types and check a fair number of foes in a pinch as well. With Hidden Power Fire, Sleep Powder, and multiple items to choose from, Roserade can be tough to predict and consistently switch into. However, relative frailty keeps Roserade from switching in on many foes that aren't passive or Water type, and even then, it needs Synthesis to consistently answer Water-types. Poor bulk also makes Roserade easy to pick off or revenge kill, and though its Speed is decent, it falls short of major threats such as Ninetales. Roserade experiences moveslot issues, as it wants both Sludge Bomb and Hidden Power to hit as many foes as possible and Synthesis to stick around longer, not to mention Sleep Powder, but can only fit two of these moves. It faces some competition from fellow Grass-types Shaymin and Virizion, which boast a Ground resistance as well as greater Speed and bulk. Unique access to Spikes and Technician Hidden Power keeps Roserade relevant, though.
