• An easy way to trigger this card's effect is by using cards like "Dark Hole", "Compulsory Evacuation Device", etc. Using this card as Synchro, Fusion or Link Material, as well as Tributing it for Normal or Ritual Summons or as cost for an effect will cause it to miss the timing, and "Yubel - The Ultimate Nightmare" will not be Special Summoned.
  • This card can be combined with "Vengeful Bog Spirit". In such scenario, the opponent's monsters will not be able to attack on the same turn they are Summoned, possibly rendering them vulnerable to this card's effect on the End Phase.
