I don't know anything about the lighting bugs. I played a death deck with 2 Bombfly and there was another card which killed the fly and when killed brought the fly back. Additional I had 2 copies of an card which could trigger the afterlife effect from cards in the void. So round a bout 10 - 12 damage alone with the fly. The deck itself was build like a zoo deck including the things I mentioned before.
I'm playing for a few years now but had a longer break when gas on ETH went crazy and you could not fuse any cards in the forge anymore.
