Hi, from what i see, this deck is nt very competitive and more of a fun deck. Anyway here is some of my suggestion :
-2 POD (why? You cannot ss when u use this and thus hinder your combo)
-1 BOM (I nt sure whether this is useful for the current playing style but i find only 1 quite useless. Personal point of view!)
+1 DAD (majority of your cards are dark and this is a must have card)
+1 Allure of darkness (Drawing power)
+3 battle fader (personal opinion as it can be use as a lvl 1 synchro material and useful when playing against meta deck)
+3 Darksea Rescue (another option for super drawing power)
+1 one for one (searching power for ur tuningware)
-6 Trap and +3 Royal Decree (Personal opinion)
As you can see, i put in more than i take out so make some amendment and see which suits you.
