I've been working on my first serious VGC team, and while I think I have a solid core (a sunny Trick Room team based around Torkoal, Comfey, and Rillaboom) I want the other Pokemon in my party to be able to cover any weaknesses they have against the dominant threats of the metagame. I'm planning to run a yet-undecided Electric-type for Pelipper, who I know can mess up my sun strategy, but otherwise all the teambuilding advice I can find tells me to prepare for long-standing competitive mainstays like Heatran, Landorus, Urshifu, Great Tusk, and Flutter Mane, which aren't allowed in Regulation H. So what should I be preparing for instead? What Pokemon have risen to fill the gaps left by the Legendaries and Paradoxes? What's good anymore?
