Purgatory knights is a control/Aggresive deck in Darkness dragon world. As a DDW deck, they can abuse all the goods Counters cards DDW have. They are turning around the ally-destruction mechanics with monsters who get enhanced when tributing a ally, and monsters who gets their effects activated when their are tributed.
Description :Purgatory knights is or a control or an aggressive deck with a lot of versatility.
They have field control (most of your monsters have more than 6k power, destruction effects), and a good defense (mad Halberd, your size 3 monster, and one of the best counter line up) which allow you to play control.
And power play such as Demios' 6 attacks play, you can aggro your opponent. The problem is that this power play is very fragile and risky.
If you call Knuckleduster, Eval grebe, Demios and equip with an item, you try to deal 11 damages, but if your opponent destroy or bounce your Demios, you only have your knuckleduster and Eval grebe which deal only 3 damages. This play is heavily reliant on Demios. And Demios has no self protection. This is why I cannot rate Damage higher than 50.
Also if you go for an aggressive play, you cannot call one of your defensive monster (Mad halbert, size 3...).
A Demios' attack formation is the most infamous part of the deck, but overall, PK have far more options than this, consequently is far from beeing reliant on this card.
And having Forever which can give you any of your Purgatory knights gives the deck even more options.
PK Forever, Abyss symfony/Life dwells into hades too and Eval grebe gives you just the ressources needed.
In term of gauge, they have very low gauge cost, and Crossbow can give you just what is needed.
I cannot give them more in terrm of power play, Size 3 + lots of protection and Demios' attack formation are the only two power plays, and the second one can easily be countered.
Match ups :Because of Demios' fragility, Purgatory knights tends to be less effective against decks with options against him. But against decks that haven't (Dragon world, Legend world) they can easily go ham and make the opponent struggle.
But overall they don't have any horrible match up because of the deck versatility.
