Should probally add Magical Scientist
and -1x Summoned Skull
+ 1x Dark NecroFear eh?

Well there it is comments plz.

*I know it’s not really considered tribute.

These are some ideas you should consider, and I will stick with cards you should be able to get fairly easily as much as possible:

Add 3x Giant Germ (they are commons now in DB1)
Add 2x Giant Orc
Add Painful Choice (also a common in DB1)
Add an Archfiend of Gilfer if you can get one.
Add Night Assailant in place of Old Vindictive Magician.
Use 2x Dark Necrofear or even 3.
