• This card can benefit from the protection of "March of the Monarchs" or "Safe Zone", however, remember to keep these 2 cards safe, as "Belial" can only protect monster cards.
  • Use cards like "Dark Illusion" and "Obsidian Dragon" in a deck based around "Belial - Marquis of Darkness" to somewhat keep him on the field longer.
  • Use cards like "Mist Body" and "Spirit Barrier" in addition to the above strategy for an almost non-removable monster while protecting your Life Points.
  • Equipping "Raregold Armor" or "Metalsilver Armor" to another monster makes it so your opponent cannot declare an attack or use spells and traps that designate a monster.
  • Combine this card with "Safe Zone" to make all monsters you control un-targetable.
    • By adding a "Prime Material Dragon", there will also be a defense against non-targeting destruction effects
