Gravitational Molestation
Well, Electric should only be sided if you have issues with mass amounts of Scrap Dragons and/or hanging Machina type shenanigans. You aren't going to do anything with that Karakuri Bureido and likely nothing with Burei.
Taking scrap dragon IS a pretty nice touch. +1 play no matter how you do it. Could either attack with it and force a trap, or use its effect to pop itself and another card.
If they don't d prison it after you attack, even better! kill itself anyways.
As for the karakuri synchros, thats harder to deal with. Summon cydra, take bureido, switch to defense, draw a card... fuse?
