Support Pokemon are those that specialize in helping their team rather than dealing direct damage to the opposing team. A successful support Pokemon build typically involves choosing a Pokemon with a combination of useful support moves and abilities, as well as investing in appropriate stats and held items to optimize its performance. For example, a popular support Pokemon like Clefable can learn moves such as Stealth Rock, Thunder Wave, and Wish, which can help its team set up entry hazards, cripple opponents with status effects, and heal its allies respectively. Additionally, Clefable's ability Magic Guard allows it to ignore damage from passive effects like entry hazards, while a held item like Leftovers can provide consistent healing throughout the battle. Overall, building a support Pokemon involves careful consideration of moves, abilities, stats, and items to maximize its effectiveness in helping its team succeed.
