Weavilelock with Garchomp C added in can be a good deck if built right. My friend runs a Weavilelock deck with Garchomp C and has one the past two tournaments. It's definitely easier to run just Weavile because there's more room for techs and such.

I would say Kingdra Prime is the next best option, but the metagame is plagued with Luxray.
