Hm, that is rather interesting Metagross66. I have only seen maybe 5 people use it, but it is certainly getting some attention :) While I don't have especial trouble with stall, the team does lend itself to being beaten by it more easily than other HO teams I have seen/used, and this has a lot to do with outrages being easy for stall teams to set up on.
While the matchup is in no way easy, you certainly can't just set up and spam random attacks and hope to win. You need to know when it is appropriate to switch (essentially whenever the opponent cannot set up and there is negligable risk in switching), when it is appriate to statup or attack, when it is appropriate to sac what is out, and when it is appropriate to switch to something to sac. People pretend that making/playing HO teams is easy and mindless, but any team is mindless to play once you know how to play it! In my opinion, HO has a very steep learning curve to start with, and then things get pretty easy, but you still have to start with a good team.
Also, as far as the ability to beat revengers vs a weakness to stall thing, I think that it must be noted that stall teams are becoming more and more reliant on revenge killers like Jirachi and Latias. This is good news for my team obviously.
While my double-outraging team may have some problems because of these outrages, my team is rarely walled. Almost everything is an easy 2hko. The difference between this team and rotom-walled ones is that rotom-walled ones can be walled (Skarmory, Rotom, and Celebi can beat everything on the team unless you put in something that forces them out), while this team can't. The thing is that when rotom and a couple of specific counters are destroyed, that team goes nuts. My team still has the possibility to lose because of its outrage dependancy.
In that last paragraph, I mentioned that it might be prudent to add something that can set up on and kill the thing your team is countering, and this is really just to force it out so that the next time it comes in it eats rocks and immediately faces something set up. This is very important for these teams, otherwise rotoms, etc. can just rest when you bring in the next sweeper, and you have failed to do any lasting damage. Successful HO teams have stuff like that. For example, most Rotom HO teams incorporate Infernape for this reason, and Stathakis incorporated Specs Jolt on a team that is supposed to be walled by bulky waters. These pokes are important because they allow you to force the switch and keep the pressure on that particular pokemon simply by keeping it from recovering and racking up hazard damage on it.
