This is not necessarily the most competitive list out there but still a hell of a lot of fun to play. It is all about make Archaon a 1 man killing machine that doesn’t want to die.

The whole list revolves around Archaon and keeping the necessary hero’s in range of there command ability’s. The Plaguebearers are primarily used as chaff to screen Archon so he himself can stay quite mobile picking off anyone he wants, using the Palasade and shackles to help you choose where you want to put him. You can also use the plaguebarers to hold objectives, but lets be honest your bringing this list to slayer of kings everyone not win the game.
The whole aim of this list is to sit your poxbringer in the backfield somewhere out of unbind range so he can set the wheel to +1 to wound on a 6+(preferably on arcane terrain to make it a 5+). Then with the Lord of Khorne close on his tail the Slayer of Kings is now going of on double 4’s. As if that isn’t bad enough for you opponent your Keeper is now letting him pile in twice for another bite at the apple.
Admittedly you will be throwing Archaon into the thick of it, that’s why where running Nurgle. He already gets a 5+ save against mortal wound and a 4+ignore spells, now with the Harbinger of decay were adding anther 5+ disgustingly resilient to that. The addition of the lord of Blights -1 to hit coupled with a good roll on the eye of Sheerian also means not a lot is getting through in the first place. You can also cast magnificent buboes to make a hero an additional -1 to hit and mystic shield to re-roll 1’s to save.
To summarise Archaon when fully buffed can be -1 to hit in combat and to shooting(potentially forcing the enemy to make extra rerolls with the eye os Sheerian), ignoring spells on a 4+, mortal wounds on a 5+, all this on a 3+ save rerolling 1’s with a 5+ save after save. On top of all of this the lifeswarm can be healing him as well as the Nurge head on Dorgar.
