This Legion is even better than 'Psychicer'. The help of two vanguard is really useful and effective especially that pressure they have for the deck. I have combined various cards and not just focused on sub clan, not all clans have a good pure sub clan that can be used without mixing other cards together. Thanks to this unit, you do not need break ride, in fact break ride can be out of the way and you can just focus on powering up. Since 'Dark Irregulars' is a soul charging type deck and rarely soul blasts, it is quite difficult to get rid of four cards from the hand and build up the drop zone.
'Amon's Leader, Astaroth', which is really the 'Amon's Leader'. This card is the main unit to power up all the other cards in the deck. Now having this unit will likely mean you will not need break riding even though break riding was really helpful. I guess not in these types of deck. Of course 'Amon's Leader, Astaroth' won't be deadly itself without using cards from 'Dark Irregular' clan rather than 'Amon' sub clan.
This first effect is so deadly and I will say better than 'Reijy' because this unit gains +1 critical for each ten cards you have in the soul. 'Dark Irregular' is known for it heavy soul charging and having like twenty cards is a simple job for this clan. The only problem that you will need to face is to prevent from decking out. No one like decking out especially if they have one unit that can put a huge pressure against your opponent.
When one of your opponent rear guard is retired due to an effect, you can soul charge three cards, if you have 'Amon' in the same column as this unit. So basically Legion will be a better option rather than adding 'Gywnn' and 'Bloody Calf', but they do increase the soul charging even if you do not Legion. Legion is just a quicker choice to do things and it will also gives you more room to add other units to the deck. Unfortunately this skill is only once per turn, so if you used it effect already you can't use it again.
Looks like 'Amon' is an important asset to the deck. Not only it gains 1k for each cards in the soul, but by paying one counterblast and moving one unit to the soul, your opponent chooses a card to retire. Quite a handy skill since you can use it as many times as you want, by I will just use it once or twice for Legion skill to activate. You just do not want to waste a lot of counterblasts on this card skill. You want to do it once or twice since this card skill will be very useful for other cards as well.
This card on it's own is still as power as Legion or in fact one of the powerful grade 3 who does not have Limit Break or the need of Legion. The only problem with this card is the 10k based power, but I guess that not a huge problem for a card that focus on powering up during your turn.
What's better than using the good old 'Dimension Creeper' engine to build up the soul dramatically. By soul blast this card, you can soul charge two cards from the deck. It is especially good when you need more cards in soul. As well this card is especially useful with some combination that combine this card with other cards to make the ultimate deadly combination.
Most of the soul charging will be done during the main phase, and that is where the deadly power rise. It does not matter if you have got this on the rear guard because you can move it to soul using normal 'Amon' skill as well as letting 'Amon' making your opponent retiring a unit. So there is no lost coming from there and this is what I like about using normal 'Amon'. Before using 'Dimension Creeper' engine, if this card is on the rear guard there were no way in getting this card to the soul but now I think this makes it easier.
Powering up just the vanguard just isn't the best way to do things because your opponent can just do a 'Perfect Guard' and the card is wasted. But if you focus on rear guards as well, this is why I love this new 'Dark Irregular' Legion build, it will make it much harder for your opponent to guard all the attack, especially now when soul charging is not done one at a time. It is done using either two or three soul charging making these units so much better. You might not know, you could get a 60k column with just these two unit combined and of course your opponent will need to focus on your vanguard critical skill which will be a pain for them.
What's better than bringing out 'Doreen' and 'Izaya' full potential than just relying on 'Dimension Creeper' and 'Astaroth' skill. Don't forget since it is an 'Amon' deck we should never forget to add these cards in the deck to power up our soul charging for the deck. When there is 'Amon' on the vanguard, you can soul charge two cards from the deck and soul charging two cards means giving 'Doreen' and 'Izaya' a 6k bonus and not to mention other soul charging you might do to make those cards even better.
