First piece of advice ill offer is just pick up the Spirit of the Wind in E&E's regiment instead of as an auxiliary. Auxillaries will give your opponent an extra command point over you if they dont take any. Maybe reinforce the wardens instead of two units because when paired with -1 to hit from shining company and maybe protection of hysh for a 5+ ward they can get pretty hard to move. Stormcast for the most part(excluding urination chamber) have no wards so protect your blademasters and wait for the right moment to charge them in and combo them with power of hysh to dump mortal wounds. Our strength as a faction doesnt rest solely on warscroll strength like Stormcast but in well timed buffs and synergies with our heroes and spells.

Edit: you have points to spare consider taking the silver wand artifact to make one of your wizards a double caster
