Grass types have their issues both offensively and defensively, but I still like to use them. I've used grass type starters, especially Torterra and Serperior and liked them a lot. I also like offensive grass types like Roserade and Breloom as well as more defensive ones like Ferrothorn that can take advantage of Leech Seed and powder moves that grass types get. I also like to use electric types because they are both solid on offense and defense. Some I've used and liked are Magneton/Magnezone, Ampharos, Luxray and Rotom. Thunder Wave is a also very useful status move most electric types get.
