This deck easily swarms the field with the effects of Il Blud and other cards by special summoning monsters from your hand and reviving monsters in the graveyard. Then with Beatdown! to boost your monster's attacks, mercilessly overpower your opponent's monsters.
Il Blud is excellent for swarming the field. With his effect you are able to special summon zombie-type monsters from your hand or graveyard, even high-leveled ones can like Red-Eyes Zombie Dragon or other Il Blud can be summoned for free.
Gozuki can be use to send zombie-type monsters from deck to the graveyard where they can easily be revived or, if you have a zombie-type monster in your graveyard that isn't Gozuki, you can send another Gozuki to the graveyard to activate his effect and special summon a zombie-type monster from your hand.
Il Blud will usually be the foundation of your swarm. If he gets destroyed other monsters special summoned by his effect will also be destroyed. That is why you need cards to protect Il Blud.
Enemy Controller and super rush headlong are both quick play spells that can be used for either offense or defense. Enemy Controller can be used to change the battle position of an opponent's monster and prevent an attack, or used to take control of your opponent's monster to open for a direct attack.
Declare an attribute after using Super Rush Headlong, all monsters of the selected attribute that your targeted monster battles will immediately be destroyed by the effect of Super Rush Headlong. This effect can be used defensively to during your opponent's turn or as monster removal during your turn.
Mirror Wall halves the attack of all your opponent's monsters that attack while it is face-up. Use Mirror Wall to force your opponent to end their battle phase.
Gemini monsters, like Il Blud and Heavy Knight of the Flame, need to be re-summoned while on the field to activate their effects, but by equipping Supervise you can have them gain immediately gain their effects. Additionally when supervise is sent to the graveyard while face-up you can special summon a normal monster from the graveyard.(Gemini monsters count as normal monsters while in the graveyard.)

I recommend putting in one bone crusher in here. Dumb it with gozuki and then il blud can ss him from grave triggering his pop effect. Since he dies in the end phase you can use il blud effect again next turn to pop more back row
