I've been using this set for a few months now and didn't see any mention of either Stealth Rock or Toxic in the analysis, so I made this set.
[SET]
name: Supporting Groudon
move 1: Toxic / Roar
move 2: Stealth Rock / Thunder Wave
move 3: Earthquake
move 4: Dragon Claw
item: Leftovers
nature: Adamant
evs: 252 HP / 32 Def / 60 SpD / 8 Spe / 156 Atk

<p> Groudon, while commonly seen as a dominating physical sweeper can also play the part of support, hindering the walls that usually stop it. With access to fantastic utility moves such as Stealth Rock and Toxic, sturdy defenses and massive Hit Points, Groudon can survive a wide variety of hits while setting up. </p>
<p> The premise of this set is to lure in walls like Lugia and Cresselia and then proceed to break them with Toxic. The pair, arguably Groudon's greatest counters are almost immediately shut down by Toxic. Lugia and Cresselia can only recover off the staving effects of Toxic so many times before falling. Any walls that are immune to Toxic, steel-types such as Dialga, Forretress and Skarmory all take a hefty beating out of Fire Punch or Earthquake. Roar is an option to phaze and scout an opponent's team, again, constantly whittling down the opposition if Stealth Rock is up. </p>
<p> Stealth Rock is an all-purpose utility move, that also greatly damages Lugia. In tandem with Toxic, this residual damage can add up very quickly, on almost any pokemon. The pair will leave your opponent, trapped between a rock and a very hard place. If they stay in, they will be whittled slowly down by Toxic and if they switch out, Stealth Rock will batter them next as they come in. Thunder Wave is an option, if you dislike Stealth Rock or have another pokemon to set up such hazards. Together with Toxic, Groudon can utilize the age old strategy of double-status. First poisoning a defensive wall like Lugia, then paralyzing an incoming sweeping threat such as Mewtwo or Kyogre. When paralyzed, such threats are of little danger, disabling their ability to switch in again as Groudon can shoot off two Earthquakes before either make a move. </p>
<p> Dragon/Ground gives phenomenal type coverage in Ubers hitting almost everything for at least neutral. Fire Punch may be used over Dragon Claw if your team is threatened by Spikes coming from the likes of Forretress or Skarmory. However, this will leave Groudon very vulnerable to Rayquaza who is immune to Earthquake, nullifies the sun's boost on fire attacks and resists the weakened the Fire Punch. </p>
<p> The EVs invested in Special Defense, in conjunction with maximum Hit Points are tailored to the current Metagame. They ensure that Lugia's Ice Beam is a mere 4HKO giving you ample time to set up Stealth Rock and Toxic. Groudon is also, only dealt a 3HKO by Latias' Dragon Pulse after factoring Soul Dew and Leftovers. In the mean time, you will be able to wear away at it's durability by poisoning it or just by using Dragon Claw. The EVs placed in Defense will guarantee your survival against an Outrage from a Jolly Rayquaza with one Dragon Dance under its belt. </p>
<p> This set still has trouble dealing with Giratina, as it can simply remove it's Toxic status by resting, simultaneously threatening with Will-o-Wisp. Supporting Groudon, as the name implies is not meant to sweep, even after the opponent's walls the have been brought down. It is best used alongside Physical sweepers like Bulk Up Dialga or Dragon Dancing Rayquaza, as the pair can beat Giratina one on one. </p>
