Deck is a bit all over the place. Defensive Traps are not robust enough for this deck to stall for time, especially since you have 4 on-attack Traps and 2 Dark Bribe. Marmamaid seems a bit random. The rest is probably ok ... mostly standard? I haven't looked at a definitive list so I do not know if your card ratios are off but 3 Magileine and 3 Messengelato are definitely fine - I like triple Cruffssant but that is just me. 1 Fossil Dyna and 1 Malefic Stardust seem ... badly thought out. Why not run 2 Tragoedia instead (or simply go to 2 Fossil Dyna)? Especially because this deck really likes Tragoedia. Alternatively, go to 2 Fossil Dyna or 2 Malefic, but I'd recommend 2 Fossil Dyna instead of 2 Malefic if you don't run Tragoedia.
