xRob75s OU Team

Hello there! Your team is structurally sound, I just wanted to make a few suggestions that you could perhaps try out to make your team a bit better.

The core of Heatran/Gyarados/Ferrothorn makes a very potent offensive/defensive presence within the team, and is backed up very well by a support Jirachi as well as two quick checks to many common threats in Gengar and Latios. My main concern with this team comes not with the team's synergy and ability to work with one another, but rather how your team fares against certain playstyles, mainly revolving around spikestacking. When using Latios, Ferrothorn, and Jirachi, this is very inviting for pokemon such as Forretress or opposing Ferrothorn to switch in on moves that it can wall, and can hurt your team if it manages to get a few layers up. Balance and Stall based teams can pose a threat despite your plethora of offensive threats as they can pressure you into switching and whittling down your team.

For some minor changes to your team, I can see some roles being switched to different pokemon in your team due to their natural versatility. In other words, I can probably see you moving Stealth Rocks from Jirachi to Heatran while replacing Dark Pulse. While Dark Pulse may have some surprise factor, there isn't much of a need to use Heatran to deal with Latios or other Psychics that can potentially kill you with Surf or Focus Blast etc. when you already have a specially based Jirachi. You can choose to run Body Slam on Jirachi instead, which helps distribute paralysis while still staying on the offensive. Thunder Wave is another option as well, but Body Slam has the potential to paralyze common switchins to a defensive Jirachi, such as Garchomp or Landorus, both of which are very threatening to most any team.

Consider Trick on your Latios. This gives you another weapon to use against more defensive teams who take advantage of walling your pokemon to oblivion. Thunderbolt has decent coverage, but when you are using Latios whose Draco Meteor is usually stronger barring a 4x weakness to electricity, it doesn't seem worth it. This will make your opponents think twice before attempting to switch in a defensive Jirachi, Ferrothorn, or Blissey/Chansey against your Latios.

If you're running a Life Orb on Heatran, then using a move like Lava Plume is rather contradictory. Life Orb Heatran should be hitting as hard as possible, and you waste precious health on your Heatran for a weak move such as Lava Plume, when one of the main perks to using a LO Heatran is a boosted Fire Blast coming from base 130 satk. Sometimes, burning your opponent is nice -- but the extra damage you get from using Fire Blast is even better.

Disable Gengar is a rather valid option for you to choose, although my personal preference is to use Destiny Bond, which is a bit more uncommon. Destiny Bond provides you a last ditch effort to kill many pokemon, and works very well in tandem with Substitute should your opponent feel pressured to switch. Using Destiny Bond Gengar nets you more two for ones than that of Disable Gengar, which many players with higher ratings on the ladder will usually try to play around. You may choose to keep Disable Gengar -- and that's perfectly valid, but you should try Destiny Bond Gengar and see if you like it.

In brief, my suggestions are to simply replace SR with Body Slam on Jirachi, SR and FB over Dark Pulse and Lava Plume on Heatran, Trick over Thunderbolt on Latios, and Destiny Bond Gengar over Disable. This seems to be a very solid team, and I wish you nothing but the best in your team's future endeavors! =)
