Call of the Mummy is very powerful if you get the right cards early in the game. If your opponent controls a monster you control none you can special summon any zombie-type monster from your hand no matter the level. This could drastically tilt the game in your favor if activated during your first turn.
Gozuki and Samurai Skull can both mill a Zombie-type monster out of your deck, once per turn for Gozuki and once during Normal summon for Samurai Skull. use them to send high leveled Zombie-type monsters to the graveyard to later be revived. In addition both of them have effect that special summon monsters. Gozuki can special summon a Zombie type monster from your hand when he is sent to the graveyard. And Samurai Skull can special summon a level 4 or lower zombie-type monster from your deck when he leaves the field because of an opponent's card effect.
Revive Zombie-type monsters in your graveyard to quickly swarm the field.
Resummon Il Blud to use his effect and special summon a Zombie-type monster once per turn from your hand or from either player's Graveyard. Although, keep in mind that these monsters will be destroyed once Ilbud leaves the field.
You will want to at least One "Anti-Magic Arrows" Mainly to stop "Wall of Disruption" and other annoying cards. I would advice to take out One "Il Blood" and one "Despair from The Dark" for the two Arrows.
