Alright, since your goal is to clear the field then I definitely suggest Ojama Delta Hurricane and The Great March of the Animals. I'm sure you're familiar with the Ojama OTK. If not, here's the info.
First find a way to bring the Ojama Trio (Yellow, Green, and Black) to the field. Tri-Wight helps if they end up in the Graveyard. Next drop Ojama Red and fill your field. If done right, you should have five Ojamas on your field. Play Ojama Country, flipping their ATK and DEF. Next, play the Great March of the Animals. With 5 Ojamas on the field, they all get an ATK boost of 1000. And finally, clear the opponent's field with Ojama Delta Hurricane (reason you need Yellow, Green, and Black). Only Battle Fader and Gorz can stop you once you declare the attack. Otherwise, each Ojama should have 2000 ATK, enough to win the game.
I don't think Ojamas can be competitive in this format, but with a powerful OTK, they don't need to xD
