Water types, are my official favorite. My top 5 favorite Pokemon (in order: Dewott, Buizel, Oshawott, Samurott & Floatzel) are all water types. My top 4 favorite attacks are Water Types as well (Surf, Aqua Tail, Scald, Aqua Jet). I can also use them to surf across the water.
what about my other favorites? - Water first, then I like in order:
• Fighting types (mainly because of Mienfoo, Mienshao, Timburr, Gurdurr, and Conkeldurr)
• Normal types (Watchog, Patrat, Bibarel, Linoone, Zangoose), they can learn attacks from other types
• Grass types (Snivy, Servine, Serperior, and starting to like Leafeon as well)
