Swarm the board with Ojama and Melffys while getting 2
Kalantosa, Mystical Beast of the Forest on the board or in the graveyard. Then summon a
Joyous Melffys each turn to reuse your 2 Kalantosa to pop 2 cards each turn as a quick effect on your opponents turn to grind them out. If your opponent has a monster that can't be destroyed by card effects or targeted and can't be swung over using
Ojama Emperor you can use
Joyous Melffys effect to attack directly then go into
Divine Arsenal AA-ZEUS - Sky Thunder and use its effect to blow up the board.
Other than that use
Ultra Polymerization,
Cattle Call, and
Ojama Emperor to summon or resummon your fusion monsters and lock your opponent out of monster zones. Use
Ojama Pajama or
Ojama Country to search and discard or just discard
Ojamagic early on to thin the deck and give yourself discard fodder while setting up for
tri-wight. Unless you know your opponent can't use the tokens, never set
Ojama duo, just get it into the grave asap with discard effects.
