so just so i understand how to play this deck. you want to summon a ojama knight on ur first turn block 2 zones. and then get another ojama knight or wait until last turn as well. cuz what if he lava golems you?
With either Ojama King or Knight on your field locking it up (You need to lock 2 slots to prevent Des Gardius as it can overpower you) While waiting for last turn, you can set your poly/secret pass/union on the field, gather another 3 Ojamas in your hand, fusion another King or Knight on last turn, Ojama Country activated, Vassal the usual drill, boom its game. Don't forget bout Anti-Magic Arrows.
Xing Zhen Hu coz he has 1 Nightmare Wheel so hope you lock the correct 1. You only need 1 copy of Anti Magic Arrows so you can farm Arkana lvl 20 for it.
