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

===Raven Castellan===
Not much to say here- if you've been paying any attention to competitve 40k you've already seen this. Take a House Raven Castellan, give him Cawl's Wrath, and pop Order of Companions. Split your fire and take out two tanks a turn, or focus down on that pesky Tesseract Vault. Costs an arm and a leg in CP and requires a screen, so ally in some Guardsmen and fire away.

*Some recant rules changes to the game and the Castellan itself mean that this is no longer the game-breaking meta-warping combo it once was, firstly the castellan went up by 100 points making it over 700pts (over 1/3 your list at 2000pts). It can no longer get an invuln higher than a 4++ and many of its stratagems went up in CP cost dramatically. Just as if that weren't enough, you can now only gain 1 CP a battle round so there's no way to make up for the increased stratagem cost.
**Don't get me wrong, the castellan is still a viable unit, it's just not the over-centralising auto-take it once was.
