Is my Unova pokemon team good?

I have Serperior, Haxorous, Golurk, Eelektross, Darmanitan, and Gigalith, all level 100's. Serperior knows frenzy plant, leaf blade, giga drain, and leaf storm. Haxorous knows outrage, draco meteor, giga impact, and dragon claw. Golurk knows night shade(scince he's level 100 it has 100 base power), focus blast, fly, and dynamicpunch. Eelektross knows thunderbolt, thunder, zap cannon, and thrash. Darmanitan knows fire blast, flare blitz, earthquake, and focus blast. Gigalith knows earthquake, stone edge, explosion, and hyper beam. If anyone has any suggestions on different pokemon for my team or different moves for my pokemon, I'm open to suggestions, because I just want some other peoples opinions.
