The deck is a 8 year progress in work. It's mainly a reaction based deck since it plays off well on what you can do to fight back your opponent. Unless they implement a card that lets me spec wightprincess, or wight prince directly from my deck upon normal summon.
There's always something that comes out that helps somewhat. so I'm always playtesting it against the current meta to make sure it can match up and win.
golden lord, floodgates, golden lands, evenly matched/struggling battle are your key control cards.
golden lord is a starter control card. send him and haunted shrine to the grave. to target send cards directly to the grave from field. this is usually when you have no cards on field. if they chain called by the grave or something. you reverse counter chain with haunted shrine from grave removing their target. and that would allow golden lord to flow freely.
if you can't bring out another monster to target with union carrier to mill out wightprince directly from your deck. equip golden lord himself, to union carrier. then proceed to set the conquistador. so you can pop cards.
evenly matched/struggling battle are just for those completely bullshit decks that you can't fight or get rid of that have like 3+ spell cards and field spells out and you can't get rid of them through normal means. literally just skip a battle phase. use evenly matched/struggling battle at the end of the battle phase from hand and nuke their entire field.. (because it doesn't target, and it isn't exactly affecting the cards themselves. This card is bypassing a lot of protections because it is targetting the player, not the card.)
I tried to make this deck give as many ambiguous answers as possible so it can be fluid during combat.
but the basic stratgy involves normal summoning wightprincess/wightprince.
wightprincess mills wightprince.>wightprinces mills lady and wight, and skull servant since it's not once per turn you can keep milling even further. by proceeding to banishing wightprince from grave and bringing out a king of skull servant. link into union carrier and equip golden lord, wightprince, or doomsday horror to return all banished dark cards to grave.
wightprince>link into linkuriboh>Mill out lady in wight and skull servant. Bring out king of the skull servant, then link into union carrier.
The chaos creator is used to spec back union carrier to give you even further options of controlling your deck. say for example you started with garbage hands like 2 skull servants into your hand. you would've discarded the 2 skull servants somehow. Then proceeded to banish them with wightprince or chaos creator, and then send back the excess skull servants back into the deck to balance it out, and special summon wightprince>linkuriboh from grave, or xtra deck to mill back the cards you send directly into the deck.
