Need help dealing with Sidhe Lords

[Phonics]

hey.

I'm currently playing MA Ermor vs Eiru and getting slaughtered by the Sidhe Lords.

They keep stealing my provinces and taking out any armies I throw at them at the moment.

They cast body ethreal, luck, resists etc and start spamming thunderbolt (?) that absolutely destroys even the largest stacks of chaff i can throw at them. I dont have any real thugs avaible except Wraith Lords soon.

This is my own idea and I have no idea if itll work:

Wraith Lord powered to A1 with Starshine Skullcap, amulet of magic resistance and Shroud of the Battle Saint for the A9 bless I have on my pretender. I have no idea what weapon would work since the Sidhes are cold resistant Frost Brand is pretty much useless. Maybe Doom Glaive? Boots of Flight to get to them fast before they start pounding me.

Thinking of scripting Resist Magic, Personal luck, Astral shield and hoping for the best.

This is just my noobish take on things so I have no idea if it'll actually work.

Any help is appriciated and sorry for the nooby question
