>>58608818Thunder Wave for Paralysis plus Charm and Struggle Bug to lower the opponent's attack power means I can cripple an opponent's lead or a certain problematic Pokemon, then swap to one of my other bugs who can set up and attack. There were some really dangerous threats that I don't know how I would have beaten without Illumise weakening them. Plus, I'm also not using items in battle, so Illumise providing healing with Wish is also nice.
