Deck Summary


Paradox is unable to field any monster removal or debilitating effects, making them highly vulnerable to The Unhappy Girl/Holy Guard lockdown decks. Almost any version of an Unhappy Girl farm deck will work against them; this one has been optimized for 8000 Duel Assessment Points without any glossy or prismatic cards.

What is Unhappy Girl Lockdown?

If you are unfamiliar with The Unhappy Girl farm decks, the basic premise is using UG's effect to prevent your opponent's monsters from being able to attack or change battle position, rendering them useless. You can also search for UG via Rai-mei's effect if you do not draw UG in your starting hand. This lockdown should be maintained until the final turn when you buff up Vassal to over 10000 ATK

How to Play

The deck is very straightforward to pilot; once you draw The Unhappy Girl, summon her and attack whatever has the highest ATK on your opponent's side of the field. You are protected from Battle Damage due to Holy Guard, and don't have to worry about getting low in LP. Any time Paradox summons a new monster, make sure to attack it to lock it down. If you do not start with UG, set or crash Rai-Mei to activate her effect.

Note: You can activate 1 Hieroglyph safely; hold or set the other 2 until the last turn, or your LP will be within kill range. 

End Game

On your second to last turn, with 2 UG on the field:

  • Tribute a UG for Serket --> BEUD

On your last turn:

  • Summon Vassal
  • Secret Pass on Vassal
  • Pop both Union Attacks
  • Attack directly for >10000 damage


Core Cards
Card Explanation

The Unhappy Girl's effect prevents any monster it battles with from declaring an attack or switching its position and prevents it from being destroyed by battle as long as it remains in face-up attack position, making it one of the best lockdown cards in the game when paired with Holy Guard, which allows you to attack your opponent without receiving Battle Damage. As soon as you draw her, being locking down Para/Dox's monsters by attacking whatever has the highest ATK on the field. They will not attack into The Unhappy Girl unless they can deal lethal damage, which they will be unable to field in a single turn.

Try to run 3 copies for consistency.

Rai-Mei's effect allows you to search for a Level 2 or lower Light Monster when destroyed by battle. This allows us to search for The Unhappy Girl if we open with Rai-Mei.

Try to run 3 copies for consistency.

Gravekeeper's Vassal's effect converts all Battle Damage to Effect Damage, which combos well with Union Attack. In your final turn before you deck out, Normal Summon Gravekeeper's Vassal and activate Secret Pass to the Treasures and 2 Union Attack to deal 10k Effect Damage directly. 

Only 1 copy is needed.

Secret Pass to the Treasures

Secret Pass to the Treasures allows 1 monster with 1000 ATK or less to attack your opponent directly. This will be used on Gravekeeper's Vassal on your final turn. 

Only 1 copy is needed.

Union Attack

Union Attack increases 1 monsters ATK during the Battle Phase by the combined ATK of your other monsters at the cost of the other monsters not being able to attack and the negation of battle damage. This condition can be ignored due to Gravekeeper's Vassal's effect.

2 copies is required to reach 10k damage; you can also run 1 copy with Spell Reclamation.
