#ArchaonYes or #ArchaonNo

[Beliman]

Simple question: can Archon, in a mono-god army, use their Allegiance Abilities?
Archaon gained the Warmaster ability:

Quote

‘WARMASTER: This unit can be included in a Blades of Khorne, Disciples of Tzeentch, Maggotkin of Nurgle or Hedonites of Slaanesh army. If it is, it is treated as a general even if it is not the model picked to be the army’s general, and you can still use the army’s allegiance abilities even if this unit is not from the army’s faction.’

I understand that this ability is just to not break any mono-god allegiance with Archaon, but the new FAQs changed all mono-Gods keywords to a new non-keywords labels:

Quote

Replace all references to a ‘Khorne army’ with ‘Blades of Khorne army’.

Replace all references to a ‘Tzeentch army’ with ‘Disciples of Tzeentch army’.

Replace all instances of ‘Nurgle army’ with ‘Maggotkin of Nurgle army’. In addition, ‘army with the Nurgle allegiance’ should be read as ‘Maggotkin of Nurgle army’.

Replace all references to a ‘Slaanesh army’ with ‘Hedonites of Slaanesh army’.

So, Archaon have all this keywords, but he is not part of their "army". So, what is a "Tzeentch/Nurgle/Khorne/Slaanesh army"? That means that ALL battletome's keywords are changed? From the entire game? Only from warscroll? Nothing has changed?

Answer: Archaon can still benefit from all allegiance abilities because they are all based on the god keywords; Tzeentch, Khorne, Nurgle, Slaanesh, Hedonite, Daemon or Mortal which Archaon all has.

Explanation: 

In the tzeentch battletome the word "Tzeentch army" that is to be changed too "Disciples of Tzeentch army" is listed 15 times. Yet none of these describe important rules or abilities. for example:

Quote

COMMAND TRAITS: Abilities available to the general of a Tzeentch army if it is a HERO (pg 72-73).

which now becomes:

COMMAND TRAITS: Abilities available to the general of a Disciples of Tzeentch army if it is a HERO (pg 72-73).

the rules for their allegiance ability says "Tzeentch unit" not "Tzeentch army": 

Quote

Instead of making one of the rolls from the list below for a friendly TZEENTCH unit, you can spend one or more of your Destiny Dice. The result of the roll you would have made is replaced with the value on the Destiny Dice you spent. For example, instead of rolling a dice to see how far a TZEENTCH unit would run in the movement phase, you could spend a Destiny Dice to determine the distance. If you spent a Destiny Dice with a value of 5, the unit would run 5".

Maggotkin of Nurgle's battle tome has this:

Quote

BATTLE TRAITS: A NURGLE army has the following battle traits:

Cycle of Corruption: Nurgle's power and blessings follow a never-ending cycle of fecundify and decay.

Roll a dice at the start of the first battle round of any battle that includes any NURGLE armies, before rolling to see who has first turn refer to the table etc...

which now becomes:

BATTLE TRAITS: A Maggotkin of Nurgle army has the following battle traits:

Cycle of Corruption: Nurgle's power and blessings follow a never-ending cycle of fecundify and decay.

Roll a dice at the start of the first battle round of any battle that includes any Maggotkin of Nurgle armies, before rolling to see who has first turn refer to the table etc...

when we look at one of the stages of corruption it reads:

Quote

CORRUPTED REGROWTH: NURGLE units heal D3 wounds at the start of their hero phase.

Nothing changes for the other battle tomes either: Since he has the Hedonite, Daemon, Mortal and all the god keywords he benefits from almost everything that he could benefit from.

Edit: I believe the reason why they changed the way the armies are named in the battletomes is to remove confusion. If you'd take a StoD army where all models have the Tzeentch keywords you'd be eligible to use the Disciples of Tzeentch allegiance abilites (Don't think anyone ever tried this tho). Which is impossible now.

Why I'm almost certain it's not intended to block Archaon from using said allegiance abilities is because it would also invalidate the use of allegiance abilities by many of the warscrolls of those respective armies. For example Rotigus doesn't have a Maggotkin keyword, and a Lord of Change doesn't have a Disciples keyword. while they're both clearly intended to benefit from the allegiance abilities. (Both of these keywords don't actually exist in the game as of now).

Nothing changed,as kragnos,this new sentence is only so you can include them in a army that with 3.0 rules you coulnt.

I saw more people saying the same with kragnos getting allegiances skills also that dont make sense, nothing in this new rule is even close to say that
