[KnockOut51]

So my friend and I traded a much on minis that we both just werent using, I gave him orks he gave me Grey Knights. So I will list what I have and from there I hope the fellow brothers of the grey knights can help me see the path toward what to add to my force.
I have Castellan Crowe, 5 Paladins, 5 strike squad with halberds and one warding stave, 5 strike squad 3 hammers, 1 halbard and one sword. 1 Nemesis Dread with psilencer and sword, 5 purgation, 1 incinerator, 3 psycannon.
what is lacking here?

You'll need a bunch of Terminators and some Dreadknights (one will cover you at small points values, but as the best thing in the book and in my opinion one of the coolest models, you should totally max out on them) - if you run any of those Power-Armoured Grey Knights, it'll almost certainly be Purifiers, which would really want a Stormraven to get to where they can Nova to maximum effectiveness.

Grey Knights aren't a brilliantly varied army, unfortunately; Terminators and Dreadknights plus some combination of characters are basically it for the basic book. Purifiers in some form of transport, whether a Stormraven or an allied Drop Pod might make it in too.
