Hey there
first of all, i hate when people use that word 'troll' like this, but generally any set called 'troll' sucks major wang. Take your set:
This set really isn't that bulky, and it doesn't really do any damage either.
The following Pokemon can set up on it (or abuse it in some other way)for free, or nearly:
Any Substitute-using Pokemon
Any hazards user
Any Rapid Spin user or Defog User
Quiver Dance Lilligant (It will either get maximum Special Attack and Special Defense, or maximum Special Defense and Speed, or a combination of the two. Either is bad, and it can actually put you to sleep once it's maxed out one to work on the other.)
Any Rain Dance or Sunny Day user
Swords Dance Pawniard (Defiant cancels Charm)
Any Taunt user with setup moves
Any user of Wish or Heal Bell can go ahead and heal up the whole team
Any Pokemon with a healing move, especially Pain Split, can go ahead and heal itself up
Any user of Rest or sleeping Pokemon can heal/wake up
Some other shit I probably missed
By the way, any slow user of Volt Switch or U-turn can easily take the stat drop, then go to a hard hitter who will deal a huge amount of damage to you.
If you use Toxic, you get rid of some (though not all by a longshot) of these, but Swords Dance users such as Feraligatr and Samurott, who have priority as well, can also set up, as can various Dragon Dance users.
In addition to this, any defensive team at all doesn't care about you, at all, and will just either hit you with a status-preventing you from healing, ever-or force you to switch out of said status and hit some other Pokemon instead. Also, Knock Off will stop you from healing.
On top of all that, you're not that bulky.
252+ SpA Life Orb Ludicolo Hydro Pump vs. 252 HP / 252+ SpD Stoutland: 153-183 (40.9 - 48.9%) -- guaranteed 3HKO
(153, 156, 157, 160, 161, 164, 165, 168, 169, 172, 173, 175, 177, 179, 181, 183)
-1 252 Atk Silk Scarf Kangaskhan Return vs. 252 HP / 0 Def Stoutland: 118-139 (31.5 - 37.1%) -- 81.3% chance to 3HKO
(118, 118, 120, 121, 123, 124, 126, 127, 129, 130, 132, 133, 135, 136, 138, 139)
Although these are fairly powerful hits in the NU metagame, they're not boosted by any item. Now, neither of these calculations would be so bad, but the fact is, you can't really force either to switch out! Although you can hit Kangaskhan with a Charm, that won't stop it from outspeeding you and attacking you again(you're not faster than almost any Pokemon that is interested in its Speed stat), and Ludicolo can take a few Snarls before it has to switch out. Meanwhile, you've taken a very large amount of damage, probably preventing you from doing something like this again, and although you've forced the opposing Pokemon to switch out, you haven't really accomplished much beyond this...and on top of all that, one of the above Pokemon is probably switching in to set up on you or something of that variety.
In short, although the set is annoying ("trolly") you're really accomplishing very little;at best, it will serve as a roadblock to some Pokemon who are weak to Rock or Dark, and stall for a bit, basically accomplishing very little. Of course, at worst, you'll allow some Pokemon to set up for free and sweep your team. Finally,
-2 252+ Atk Choice Band Mold Breaker Sawk Close Combat vs. 252 HP / 0 Def Stoutland: 342-404 (91.4 - 108%) -- 50% chance to OHKO
Even should you predict the switch-in of a powerful Fighting-type and use Charm, you'll still be hit very, very hard.

"team him up with a shadow tagger in doubles and enemies become nearly helpless."
I really doubt that, but in any case, that's not relevant at all to this forum as it's not a doubles forum, but rather an NU one, which you seemed to understand by talking about how it's a decent lower tiers tank. (Even if there was an NU doubles tier and this forum was the place to suggest things for it-nope and nope, by the way-, there aren't any Shadow Taggers down here, so that's irrelevant anyhow). Don't just toss out all the merits of a Pokemon if they're not relevant to hype it up, that just weakens your argument.
