This deck revolves around phantom knight cards and burning abyss cards. It is a combo deck that is all about setting up a big board of monsters while also having back row cards to reassure that you wont die either when your monsters are destroyed or they have found a way to negate your entire board(cards like dark ruler no more, forbidden droplet etc.). This deck unfortunately is very expensive and is not a breeze to play due to the fact that you need to be mindful of what you are doing otherwise you are doomed
explaining the combo
there are many ways to combo with phantom knights BA due to their plethora amounts of extenders and choices you can do
extender cards are: psychic wheelder, kagemucha knight, emergency teleport(to bring out wheelder),tour guide from the underworld(bring out a free material to set up your plays), danger monsters (since they are level 3 and can special summon from the hand for free)and finally phantom knights of silent boots( free special summon from hand if you control a phantom knight monster.
one combo for example is tour guide and kagemucha knight
normal summon the tour guide from hand, activate the eff of tour guide then chain kagemucha knight special summoning itself, summon a graff from the deck
link away tour guide or kagemucha knight and graff to summon a cherubini from the extra
use graff eff from gy to summon a cir from the deck
use cherubini eff to send a gloves from deck to GY
use gloves eff to send a tear scale from deck to GY
link away cherubini and cir to summon rusty knights from the extra
cir effect will activate to summon a cherubini from the gy(dont summon it to where rusty is pointing at)
use rusty eff to send a cloak from deck to gy and set a blade
use cloak eff to add a silent boot from deck to hand
tear scale will activate summoning itself from gy
special summon boots from hand
xyz summon both of them into a leviair
detach boots to summon a gloves from the banish zone
link away leviair and gloves into a anaconda
boots effect to banish itself and add a blade
anaconda eff to send red eyes fusion and summon a dragoon
then you can either set the blade or keep it in hand for next turn
with two cards you just set up three negates and a board removal
if the blades go to the gy you can use them to revive any phantom knights from your gy then if you still have scale from gy you can summon it as well so you can go into an xyz for next turn
this isnt the only combo there is in PK BA there are multiples you can do and this deck can go through many negates
