I tested the necessary part of the code – here’s how it works. Each time after the phoenix/elementals die, the hero summons them again.

elemental = 0
fenix = 0
  
function DefenderHeroMove(hero)
  if elemental == 0 then
    elemental = 1
    startThread(UnitCastGlobalSpell, hero, SPELL_SUMMON_ELEMENTALS)
  end
  if fenix == 0 then
    fenix = 1
    startThread(UnitCastGlobalSpell, hero, SPELL_CONJURE_PHOENIX)
  end
  return not nil
end

function DefenderCreatureDeath(unit)
  if(GetCreatureType(unit) == 85) then
    print('fire elem dead')
    elemental = 0
  end
  
  if(GetCreatureType(unit) == 91) then
    print('phoenix dead')
    fenix = 0
  end
end
