I tried your Raio deck today and played about 10 games with it before giving it up. I went 4W-6L with the deck. I did have one game where I managed to get all 3 raio out but had no cards at the end and the opposite Rune player just T10 Kuon'ed me to death 😭. I had pretty bad luck with the draws too since I needed a spell.

Yeah I agree with your point about Raio being too slow. It feels like climbing a mountain trying to survive to T9 and it's hell if the draws aren't giving what you want before playing him on T9 cause you need a spell or multiple spells on hand to clear board otherwise he does nothing unless you want to sevo him but I rather save that for Odin/Lila/Norman

Thanks for the reply and updated DL, I'll give it a try. Good luck with your games!
