Editing Warhammer 40,000/8th Edition Tactics/Grey Knights (section)

===As Allies===

Slam-Baby
With CA2019 around the door there might be some fun to have, that is not ridiculously overpriced. 
*1 Ally vanilla Space Marines as a battalion with a librarian, he gets: Veil of Time and Might of Heroes. Both powers target <Adeptus Astartes>; guess what you are?
*2 Take a Nemesis babycarrier, if you want less points, in a patrol detachment with a Strike squat
*3 Use: Veil of Time + Might of Heroes on you Babycarrier, then hammerhand and sanctuary and toss it over the board. Give it the nemesis Lord War Lord trait, since you can re-roll charges now. With a hammer you will always do at least 4 damage per unsaved wound up to 7 - With 6 attacks you can put a dent in something. 

It is still quite expensive, and you want to send a strike squad with falchions behind him for backup (falchions do provide more from +1 to wound I guess). Also maybe take Interceptors, who can deepstrike too. In that case i would still take first to the fray on your Babycarrier, veil of time could still target a unit that is not within 6" of your warlord.

Unfortunately, as of the new Codex, Vanilla buffing powers now specify CHAPTER instead of ADEPTUS ASTARTES, so you can no longer spread buffs across to other Chapters.

HOWEVER, the [[Deathwatch]] still get ADEPTUS ASTARTES powers instead of <CHAPTER> (at least until GW FAQs it), meaning if you bring Deathwatch instead of Vanillamarines, this still works. May not be the cheapest alternative, but this does mean this strat still works.
