For doubles, the togekiss with follow me on the set up is great. However, Guzzlord should not be used offensively.
He is a blissey on steroids and should be a wall if you have him on your team. Since this is gen 7, the geomancy won't be accessible until poke bank comes out it may be awhile before you can use this but it is interesting and I think it will work well. I think that the geomancy should be passed to either a xurkitree for an offensive sweep, or tapu-fini for a more bulky sweep. here are the sets I would run, so that you could use both with or without the geomancy boost.
Xurkitree@Choice scarf
Nature: Timid
Ability: Beast Boost
Moves
Discharge (For Geomancy destruction next to your own ground type)
Thunderbolt (non-geomancy STAB)
Energy Ball (Ground coverage)
Volt Switch (Do NOT use with geomancy)
Tapu-Fini@Assault Vest
Nature: Calm
Ability: Telepathy (If you can get its hidden ability, discharge will miss you and guzzlord won't be screwed)
Moves
Muddy Water (Geomancy spread damage with potential accuracy drop)
Scald (Burn chance)
Dazzling Gleam (Geomancy spread damage)
Natures Madness (non-geomancy hyper fang for walls)
For your Guzzlord, If you want to keep him, I would run him as physical support
Guzzlord@Leftovers
Nature: Adamant (no helping his miserable defenses)
Ability: Beast Boost
Moves
Dragon Tail (Forced Switch)
Gyroball (With togekiss follow me, can annihilate fairy types)
Toxic (residual damage)
Crunch (STAB damage)
For your Ground Type to go next to Xurkitree if he gets geomancy I would use a palossand
Palossand@Assault Vest/Leftovers
Nature: Modest
Ability: Water Compaction
Moves
Shadow Ball (STAB damage)
Earth Power (STAB damage)
Giga Drain (Water Coverage and HP restoration)
Shore-up/Infestation (Leftovers vs Assault Vest)
Hope this was helpful and good luck!
