Hello!
I bring one of my Yubel decks for Yubel fans, trying to keep the main point on her but not missing oportunities to summon strong monster to make time or to actually win the duel
I'll leave here a guide, also for you to play/improve it
(The cards that are 1 copy is for you to define depending your game style, how much of thoses cards you want)
Example: More limit reverse is playing more with reborn yubel, more power of the guardian, field card and fusion deployment could help you to play less the GY
Important points:
Field card: Yubel will not need sacrifices with the field card, but wont be able to destroy her, you can make time with this, or use it when you have Ultimate nightmare, also you protect the slime god, so you can create a danger to the enemy, when you prepare yourself to summon yubel, the field wont last too much, normally your enemy will try to destroy it at all cost
Power of the Guardian: If Yubel is equip with this card, she attacks and gains a counter, she will not be destroy be her own effect if you do not sacrifice
But the idea of Power of the guardian is to equip this card to Yubel terror incarnate or Yubel the Ultimate nightmare, winning counters - attack, and protecting her to be destroyed so the enemy will have to summon a monster that later will be destroyed by yubel2 or you will attack him with yubel3 doing his effect (you can use power of the guardian in any other card you want)
Slimes: Guardian, the trap card and the god are for you to make time, create danger or sacrifice to summon yubel
Slime god is a really strong card that will make the enemy play strong cards agains him, if you play the god as you main card, when Yubel arrives, the enemy will be not ready to deal with her
Branded: Is just a easy way to create danger as i said, a mirrorjade is a strong card that only use a spell card, also during the process you can use yubel to create Lubellion, and later reborn her with limit reverse, monster reborn or any other card you normally use
Extra deck: we have number 27 that normally if he attacks you can transform him in Number81, a strong attack card that can protect a card for effects, thats for Yubel - Ultimate nightmare
also you can bring with 2 yubels the canon that deals 2000
If you feel stuck, you can use a yubel a 2 other cards to create a Black luster with his strong effect
Side deck: use floodgates, or cards that slow the game to the maximun so you can make time
Cards of the main deck:
Calculator, just summon him next to yubel and a lime guardian or lime trap card and the enemy will have to sit down
Sauge de fleur: Destroy yubel and other card on the field, and also have a good monster to a black luster or just win the duel
Phantom of chaos: copy the Ultimate nightmare of your GY as a last resort
Mystic tomate: if you find a meta player that actually attacks monster face down, you can summon yubel (most of the time it wont work)
The rest you will figure out how it works
Hope this deck finds a fan of old school cards and this amazing character/card
If this deck reach a good amount of people, i'll be sharing an amazing deck not fully about yubel, but you can summon her and the ultimate nightmare and also maybe face meta decks
Bests,
