After the infamous SkarmBliss combo made its appereance in the 4th generation metagame, trainers have sought for a new type of defence. One which wasn't that much known and that it could bring a surprise factor, as well as a nice way to cripple the opponent. This Blissey-Alomomola-Bronzong combo tries to imitate the former combo but with some major changes. Blisey acts as a Special sponge, whereas Alomomola represents the physical wall. Bronzong, on the other hand, is the force supporting this two pokemon.
Blissey is provided with Heal Bell, which heals all status changes on your team. This is a plus if you think of adding a pokemon with Rest on your team, allowing you to wake him up and save those nasty turns waiting for it to wake up. Softboiled serves as a way to recover from the continuous sponging. Flamethrower is necessary as Blissey will need to face Ferrothorn, which otherwise Alomomola would struggle against. Finally, to ensure damage and bringing slowly the foe down: Seismic Toss.
Alomomola, as said above, sponges all physical based moves. Wish and Protect is an incredible combination which lets you regenerate your team's HP (Bronzong will be pleased by it as it really needs a way of recovery), as well as letting you cripple your opponent's pokemon with toxic. Scald is prefferred over other water moves as it has a 30% chance of burning the foe, thus lowering its attack stat. Alomomola's Dream World ability ensures it to survive longer, because it will be switched continuously during the battle.
Finally, Bronzong is the Stealth Rock user and the one that resists Spikes/Toxic Spikes. Status on him isn't that important as Blissey has Heal Bell. Its moveset is pretty straight forward: kill everything which is at the verge of death thanks to Blissey and Alomomola. This is accomplished by Earthquake, Gyroball and HP (Ice), which ensures maximum coverage. You may also put Zen Headbutt to face with relative more ease Machamp and the likes of it which could be a real threat to this trio if it had Thunder Punch and Dynamic Punch. Also to note that Bronzong, in case Blissey is not capable, can take Ferrothorn's hits.
