I've been running this zong successfully, and essentially what it does is manipulate the popular conceptions of the pokemon for a 1-2 turn advantage, which helps me tremendously with my offensive team (2/5 are scarfers, they're all fast).
Trick zongs have a major downfall in that people see trick coming and just use it to wipe your team. They'll switch in their mixed/phys sweeper to take the item, then use it against you later, often giving the zong another choice item (Losing you turns). In the case of Lagging Tail, they A) Never get something they want and B) Always get one of their offensive pokemon crippled. No one switches in a wall vs a Bronzong, and my entire goal is to cripple/kill off their offensive pokemon. Even if I get tricked a choice item from them, I can still make a new move selection next turn. In the case of a choice band, it powers up explosion/earthquake. Also, Lagging Tail does not lower their speed, and hence does not cripple Gyro Ball.
I use Heatproof because no one sees it coming. I have not once been hit with an earthquake before a fire move was first used, and I'll even switch zong in on earthquake users who wouldn't be using earthquake that turn to give them the impression that he's immune. The confusion over his resistances costs the enemy a few turns, which is all he needs to seriously mess up their team.
Zong switches in vs something => They switch something else in, Zong uses hypnosis => They got slept and switched out, whatever switches in gets a Lagging Tail / They tried to kill it with a fire attack and got slept / They tried to kill it with a fire attack and got killed with Earthquake
Pretty much anything that happens with this set is benefitial to my team. He often cripples 1-2 pokemon, kills 0-1, sets up rocks, and then later sleeps another/explodes. Most of the pokemon that would kill him in 1 hit with a fire move fail to, and instead die to Earthquake, or get slept.
He dies slower than the traditional trickzong, has more utility, and is just generally much better for a fast-paced offensive team in my experience. For a stall team, this set would absolutely not work, but in the environment of sweepers I have set up 1 pokemon slept, 1 lagging tailed, stealth rocks set up and a possible pokemon dead from earthquake/explosion is pretty much a dream come true. I always loved zong with my offensive team, but this set just makes it better. What the set hopes to do is confuse the opponent, and it seems to be working quite well.
