Notes & Combos
Typical endboard I went for was Phantom of Yubel, Spright Elf, IP: Masquerena, Unchained Soul of Rage, Nightmare Pain, and an Iblee on the opponent's side of the field.
This allows you to go for the double Iblee lock. If your opponent manages to get rid of the Iblee in the first place, revive it with Spright Elf and link it away with Masquerena.
I highly preferred this double Iblee lock over Apollousa because Apollousa endboards are easier to break. Whereas for the Iblee lock, the opponent better have the out in hand (droplet typically) or link it away. If they do link it away, we can put the Iblee back onto the opponent's field again, and use either SP, Rage, or Escape to get rid of the monster they have on the field.
For the majority of my games, once I Iblee locked, the game was over. If an opponent did manage to break through the double Iblee lock, I found that they often did not have the resources left to play their actual strategy, and once it goes back to out turn, we can win the game.
This Iblee lock is also really good to include especially for hands where you don't have any Yubel access and are only playing with Sacred Beast and Unchained cards.
Also, always shotgun Phantom of Yubel if you still have plays afterwards to avoid Maxx C and other handtraps. In my experience, it is also possible to bait the opponent into an early Nibiru and continue to build a strong endboard after that.
Hope this helps!
