I use 3 ojama blues and 2 of each other. This helps you to thin your deck even faster, while doing the same job with Ojama knight. Jealous of the 3x king of the swamp!
Deck still works most of the time he won't be able to use earthquake because he clogged up his back row and he never tributes summon frostosaurus when you have knight or king on the field (without ojama country)
He tribute summoned him against me, and run over my knight. But he had 2 monsters, so I don't know if that matters. Similary, he never used his trap that boosts by 1000 atk to run over my knight. I don't know. The second time I tried it with the changes, it worked. I will test more.
Just use Chazz with "land of the ojama" as skill and your knight won't get run over by frosto saurus even with the field spell lost world knight still has 2000 atk vs frosto saurus 1700 as long as you don't attack he won't use survival of the fittest tail swipe is still an problem but most of the time is clogging up his back row and won't be able to use it
