Ironically, under MR4 this thing gets trolled by another Fusion deck, since Ojama King only blocks Main Monster Zone - the opponent is still able to Poly monsters from hand to fusion summon into the Extra Monster Zone.
Horrible! Some players use such dirty trick to summon this first turn! Cyber Stein + Ojama King first turn = GG! Even if you do have Tribute to the Doomed in your deck, it's largely a miss that you will get it as your starting hand! It's hell!
I've seen some comments about the weakness of this Deck. I've just built a deck whit the ojamas and now I'm Platinum 4 after 2 days of using it. Sure, at the beginit was easy, because the enemies didn't know how to counter ojama country. After some wins i had to rebuid the deck, because the players become stronger and stronger.. Now, many games after this, i'm looking forward to legendary. Gonna upload the deck recipe soon, if someone asks
you know in real life TCG, you can't ask what kind of deck your opponent run with. don't know if it against the rule to ask opponent his/her deck. in duel links, its the same except you can see his deck after you win or loss. but next time you duel you will never know who will run ojama deck bullshit again.
When you play a real yugioh game you got 5 monster zone and this card block 3 its ok but not if you got 3monster zone
You can use card to flip it face down to free the zones but careful cuz when flip back up, the owner can select zones to lockdown again. Soul exchange work because it will be removed form the field 1st and free the zones to let you summon a tribute monster.
