This is a Pure Voiceless Voice Deck which can be used for casual and fun play. This deck is not meant to be competitive or "meta" but it can still be used in a somewhat competent and playable way. This is also a very easy deck to learn and can be used for beginners!
The Side Deck is composed of a bunch of Ritual and Fairy support cards. As well as some extra options to add to the deck, such as Dogmatika Maximus and Nadir Servant, and Super Polymerization to make the deck have a little more options for playability. I've also seen people use the deck with some Drytron cards, so you can also consider those cards to add to the deck.
As of recent (August 2026), I also added The Fallen & The Virtuous as a very good consideration option to the Side Deck, and you can run Albion the Branded Dragon and Ecclesia and the Dark Dragon in the Extra Deck as targets. I HIGHLY recommend these cards myself.
The Extra Deck is negligible in this deck. It is used as a toolbox mainly for other cards and composed of a bunch of generic Extra Deck cards the deck can get into, Fairy and Ritual support cards, and some cards that can be discarded with Diviner of the Herald or Dogmatika Punishment, or be used as Super Polymerization targets if you decide to run that in this deck.
The goal of this deck is to use Lo, the Prayers of the Voiceless Voice, the main key piece of this deck, to bring out your Boss Monster of this deck, Skull Guardian, Protector of the Voiceless Voice, which has an Omni-Negate built into it, and the various cards meant to protect all of your Light Ritual Monsters and to interrupt your opponent's plays. The deck naturally has a lot of recursion and protection in order to keep you in the game and to keep up the fight in order to win the duel.
For this deck, the main combo will start with Lo and end with Barrier and Skull Guardian on the field. Plus any other cards you may have drawn or added for more interruption during your opponent's turn.
A sample combo for this deck is as follows (Lo, the Prayers of the Voiceless Voice in hand):
Normal Summon Lo, the Prayers of the Voiceless Voice. Activate her effect to place Barrier of the Voiceless Voice on the field face-up. Activate Barrier's effect to add Saffira, Dragon Queen of the Voiceless Voice to your hand. Activate Saffira's effect to discard herself from the hand and send Prayers of the Voiceless Voice from the deck to the grave, then add Skull Guardian, Protector of the Voiceless Voice from the deck to your hand. Activate Saffira, Dragon Queen of the Voiceless Voice's second effect in the grave to banish herself to Ritual Summon Skull Guardian, Protector of the Voiceless Voice using Lo, the Prayers of the Voiceless Voice as tribute with her passive primary effect. Chain 1 Lo, Chain 2 Skull Guardian on summon to add Sauravis, the Ancient and Ascended to your hand. Lo, the Prayers of the Voiceless Voice will Special Summon herself from the Graveyard. Pass.
The combo seems pretty simple and lackluster. But with this end board, we end with: an Omni-Negate and destruction effect with Skull Guardian, Protector of the Voiceless Voice, as well as her having 4,100 ATK with Lo, the Prayers of the Voiceless Voice on the field; as well as the effect of Barrier of the Voiceless Voice be activate, with Lo and a Light Ritual Monster on the field, allowing only your Light Ritual Monsters to be able to be targeted for an attack, AND Light Monsters cannot be targeted with card effects; Sauravis, the Ancient and Ascended in the hand which can discard itself to negate the activation of an effect that would target a Monster you control if your opponent somehow found a way to target your Monsters; and Prayers of the Voiceless Voice in the Graveyard which can banish itself whenever one of your Light Ritual Monsters you control leaves the field by your opponent's card effect to Special Summon from the hand or deck; Sauravis, the Ancient and Ascended, Saffira, Queen of Dragons, or another Skull Guardian, Protector of the Voiceless Voice ignoring its summoning conditions; and if Lo, the Prayers of the Voiceless Voice is in the Graveyard while this happens, she can Special Summon herself from the grave; Plus, any additional cards you may have in your hand to set or play as extension. And yes, you can control 2 or more Barrier of the Voiceless Voice, so your opponent has to destroy both in order to start targeting your monsters.
Overall, a pretty cool deck that I think is easy and simple to learn as well as having a bunch of powerful effects. I hope you enjoy!
