The main strategy for a Mask Deck is to prevent your opponent's monsters from attacking while damaging their Life Points at the same time. Also, "The Masked Beast", a Ritual Monster boasts a powerful 3200 ATK and "Masked Beast Des Gardius" has 3300 ATK and the ability to activate "The Mask of Remnants" upon destruction, which can take control of an opponent's monster.
One good combo is to use "Mask of the Accursed" to stop an opponent's monster and take 500 Life Points from them each turn, and use "Mask of Dispel" to damage them even further and "Mask of Restrict" to stop them from Tributing the monster. Equip Spell Cards are a good choice for this Deck because you can power up your non-Tribute Monsters while "Mask of Restrict" is in play. "Mask of Brutality", however, is often tossed out for other Equip Cards due to its cost. Ritual Monsters and/or Fusion Monsters are also a good choice for this Deck to take advantage of "Mask of Restrict". "Lava Golem" is a good choice as fits with the Burn theme and can be equipped with "Mask of the Accursed" and kept on the field with "Mask of Restrict".
Another direction is to focus on "Masked Beast Des Gardius", a Level 8 Monster with a powerful ATK and even if your opponent manages to destroy it you can take control of that monster through "The Mask of Remnants". The monster requires you to Tribute 2 monsters, at least one "Grand Tiki Elder" or "Melchid the Four-Face Beast", and "Rescue Rabbit" can be used to quickly Summon 2 copies of either of those monsters. "Union Carrier" can be used to equip "Des Gardius" directly from the Deck, making easier to trigger its effect. Consider adding "Dark Necrofear" as it has a similar control effect to "Des Gardius", and you can remove the Fiends you Tribute to Summon it.
