Azelf is a great suicide lead, don't get me wrong, it gets all the tools it needs with more than the other people can consider. That said, its main advantage over all the over suicide leads is its access to Explosion.
We now get into the set. Focus sash is obvious for a suicide lead. Ability is only levitate, 16 hp evs is to ensure that Azelf doesn't die instantly to Glimmora's Sludge wave + Poison, due to Glimmora being one of the most used leads in the game.
The other lead is H-Samurott, which we cannot deal with using Azelf unless we use our tera typing on our lead. Which the tera type Fairy guarantees that we survive most attacks.
Jolly nature is mandatory to boost our speed.
MOVES:
Thunder Wave is to severely cripple opposing leads if their mon is an offensive mon that cannot deal with Azelf, for example, Enamorus(Both forms), H-Lilligant, Sneasler, Moltres, and Glowking.
Stealth Rock is mandatory for a suicide lead, as it is literally their purpose, to set rocks.
Taunt is to stop opposing set-up leads from functioning, like as previously mentioned, Glimmora.
Explosion is to create offensive momentum as to be able to get a free switch into one of your Pokemon while discarding Azelf.
TEAMBUILDING:
Azelf should be used on hyper offense teams, as once you use Azelf, you need to apply constant pressure on your opponent as to not let them to be able to get rid of the rocks. However, Azelf cannot tolerate opposing balance or semistall teams, as they can easily shake off the lasting impact Azelf makes.
