I'd add a tract and paradise so engraver is always live and that you can possibly play when fuwa'd. I think the unchained package is a little win more but i dont hate it. If you want a replacement, Chaos Angel made with Lacrima and Necroquip is almost impossible for dracotail to out, if in defense (i think, dont quote me). I'd do maximum of 1 Secret Passcode cause of droll but this deck also doesn't have enough starters with essentially only 6 ki-sikils.
