If you summon BEWD before he synchros the 2800 atk goyo he'll never switch you to def. If you're slow you have to attack into the 2800, usually costing you 1 BEWD. I have an absurd win rate though, and this is very rare.
I was using a similar deck, and he DOES CHANGEyou sometimes to defense with jutte fighter, first 5-6 times he didn't but last time he did, but being carefull thats not much a problem and i'm using a rabiddragon too
