Why we recognize this Pokemon: Roserade was a complete monster back in D/P/P, with a ridiculous SpD stat and a high SpA stat, Roserade made a great special wall/sweeper. This generation, Roserade didn't get much new, and it fell down into the UU. But that is fine, as it does amazing in the tier. With a great secondary type in Poison, Roserade gets some useful resistances and cuts down a weakness. The secondary typing, also gives Roserade an immunity to Toxic stalls. A great ability in Natural Cure, also lets it overcome Burns, Paralysis, and Sleep, making Rest a very viable move for Roserade. Sleep Powder can give you an opportunity to stop a sweeper in their tracks while you cut them down with moves like Leaf Storm and Sludge Bomb, both of which, are great STAB moves and grant good coverage.
What makes him different from other Grass Types?
Roserade, as most Pokemon, is based on something from the real world. Roserade is a Pokemon that is, while obviously based on a rose, based off of a mysterious patron from a masquerade ball. A masquerade ball is a tradition that originated in France, where guests would dress in intricate masks and costumes to celebrate many things such as marriages, or royal events. Masquerade balls were a feature of the Carnival season in the 15th century, and involved increasingly celebrate allegorical Royal Entries, pageants and other dynastic events of late medieval court life. Masquerade balls were extended into costumed public festivities in Italy during the 16th century Renaissance. They were generally elaborate dances held for members of the upper classes, and were particularly popular in Venice. They have been associated with the tradition of the Venetian Carnival. With the fall of the Venetian Republic at the end of the 18th century, the use and tradition of masks gradually began to decline, until they disappeared altogether.
