Yeah. There's a tournament here soon and they said I could use either, but the warscroll I pick has to be in a book and have points in the GHB. So I can pick either Terrorgheist, but there's no points in the GHB for a Strigoi Ghoul King on either the TG or ZD, so I have to pick the Abhorrant GK warscroll.If you read the FAQ for the rules it states that if two war scrolls exist for one unit then you can pick which one you want to use. In my eyes that makes both the GA war scrolls for Zombie Dragon, Terroghiest, Terrorghiest with Ghoul King, Vargulf etc... and the Flesh Eater Court ones viable for use.
