I know sylvan is an archetype and konamy never nerfs an archetype (specially when there are from boxes)
But can nerf this 🔥: you don't spend gems or money to get it and makes sylvans op. Enemy always summon very powerful monsters like hermitree and guardyoak and continues to destroy your monsters and backrow by excavating his deck, and even you have still some backrow on the field, usually it will be useless to protect youself by opponent's monsters. So i think this is a true 🔥 card that needs nerfs by konami
