Battlefield spell + retreating?

Unless i'm utterly wrong, that is not true. If i cloud trapeze onto your army/SC, cast the MoD and retreat, you will die regardless of anything. Your SC might as well be "inmune to heat, shock and frost". Or "inmune to death" and still would die. Becouse after 50 turns the attacker (that is, me) would retreat. As i dont have units, just the endless phantasmal warriors, fight would keep until turn 75, at which point everyone is destroyed.

Is not that the case?

No, at turn 75 the defender would retreat. Only those who cannot/will not retreat are destroyed.

Mindless, berserk, unconscious, immobile, etc units will be destroyed, but most will just retreat.
