Try to get at least 1 Ojama blue on your side on the field and you are ready to go. (By using Ojamatch or Rescue cat or just normal summon)
Attack one of your opponent's monsters and use its destruction eff to search Ojamatch and magic(as long as there are enough of your 3 Ojamas in your Deck) to your hand then you activate Match to add blue and normal summon it to attack again but this time you can add 1 Ojamissilation.
Repeat this step but then with adding red to hand so that you can normal summon red to summon all of your ojamas in your hand ;)
(magics eff triggers and you get Ojama black, green and yellow. These are necessary if you try to activate Ojamissilation.)
Link them away to a link monster of your choice (I personally would choose Apoullousa, Saryjuya (highly recommended), Borrelsword or Abomination )
then activate Ojamissilation to summon A, B, and C by banishing 3 Ojamas from the grave (don't forget to use Ojamissilations eff to draw 1 afterward)
link them away for cross sheep and another link 2 and then summon ABC buster.(Crosshep can special one rank 4 or lower ) and if you are lucky and can summon swamp boi you can summon A to Z.
I hope you guys like it and maybe help improving it.
Long live the Ojama!!!
