You can only activate this card while "Ojama Green", "Ojama Yellow" and "Ojama Black" are face-up on your side of the field. Destroy all cards on your opponent's side of the field.
The effect of Destiny HERO - Diamond Dude can bypass the activation condition of Ojama Delta Hurricane!!, allowing you to activate it without the required monsters on the field.
Use De-Fusion on Ojama King to special summon Ojama Black, Ojama Green and Ojama Yellow to your field, then activate Ojama Delta Hurricane!!. You can then fuse all 3 together again to summon Ojama King and lock all your opponent's monster zones.
Use Tri-Wight to special summon 3 level 2 or lower Normal monsters from your graveyard (i.e. Ojama monsters)
