in a Rampardos Deck I would play:
4-4-4 Rampardos
2-2 Sandslash
2 Stantler
3-3 Gravler
any trainers you like
but have a lot of supporters. and fossil excavators
21 fighting energy
Strategy:
get Stantler out and use lead to search your deck for fossil excavators to get out Rampardos on your bench. The sandslash is mainly for a last resort if you can't get rampardos out for some reason and they can do 40 for one energy. same with the gravler.
