Alucard Hellfire

I was wondering if I have a lord of chaos on foot with a mark of slaanesh as my general, can I stack his "Reaperblade", with "into the fray"(Godseakers ability) and "Euphoric Killers" (slaanesh command trait) to auto hit with a 6, doubling the hits causing 4d6 wounds on his first attack of the game?

I use the age of sigmar app, and they have arcane bolt and mystic shield on the war scroll for evocators. Can evocators cast these?

Can anyone please give me some information about this?

Question, I have a Lord castellent with gryph-hound, under GHB2017 gryph-hounds could be played 1-12 at 40points each, under GHB2018 it is 6 -18 at 140 points/6 so can I no longer play 1/2 gryph-hounds with Lord-Castellant, Lord Veritant?
