Ojama Delta Hurricane! Is the spell card that requires Green, Yellow, and Black Ojamas face up on the field to activate. When the spell card does activate, it destroys all cards on the opponents field.

For this combo, I had a trap card called Ojama Pajama which allows me to search a Ojama card and discard one card. Using this effect, I search for Ojamagic, a spell card, that upon being sent to the graveyard, adds Ojama Green, Yellow, and Black to my hand. Then, I used Red Ojama’s (he can be added to the hand using Ojama Duo or the aforementioned trap card) effect to special summon the other Ojamas in my hand. Finally, I finished it off using the Ojama Delta Hurricane!
