Those immortal squads tend to live up to their names, as they can take most anything by themselves. The Scarabs are there because of extra points, and they might take out someones big, expensive vehicle if you get lucky. The warriors hold objectives, the harps are great for picking armor off a distant land raider, especially because 2 shots (a.k.a one round of shooting with a infinite range weapon) can reduce the almighty land-raider to being able to b e penetrated by your tesla destructors. The doomsday cannon is just sexy pieplates, enjoy those. Cycle solar pulses to make sure it gets in at least 2 rounds of shooting. On occasion, your opponent may forget you actually have other units in your army and they may become focused on killing it, which is also nice
Last but not least, don't forget zahndrekh and obyron. Obyron can teleport that squad of immortals into rapid fire range, and after that, if someone dares to charge you, obyron is a monster in
CC, and the lord has scarabs to make their big, expensive
hq punch himself in the face. Zahndrekh himself has his tactics, so you can take buffs away from people and give yourself some. What I personally find funny as hell is giving a squad of immortals counter-attack, so that if someone charges you, the destroteks have defensive grenades, so you deny them their extra charge attack and you give it to yourself insdead

The tesla squad is almost as good, not as many warscythe attacks, but does have extra scarabs for additional "stop hitting yourself" funtimes.
