Main Deck Monsters
A Burning abyss deck will comprise almost entirely of monsters, as monsters in this deck serve both as your bodies and tech tools.
Scarm, Malebranche of the Burning Abyss: 3x Copies
Scarm plays a pivotal role in BA as deck's only searcher. Depending on your opening hand, Scarm is one of the best cards to see going first or second due to the fact that it is often the best discard to summon Beatrice to mitigate the cost of summoning your boss monster. The card you will search for the most is more than likely going to be Tour Guide From the Underworld, who we will cover later.
Cir, Malebranche of the Burning Abyss: 3x Copies
Serving as the deck's Monster Reborn, Cir is by far the best card to use to summon Dante with for one of BA's more well known combos: Cir-Dante-Cir. As Cir works when it is sent to the graveyard from anywhere, upon the removal of either Beatrice or Dante, Cir will activate, allowing you to bring back Dante for both defensive and offensive purposes.
Farfa, Malebranche of the Burning Abyss: 3x Copies
Farfa serves as the decks primary tool for disruption. Able to be utilized in various ways, Farfa operates best either in the deck or as a material for Dante for a quickplay banish. This card is also a good target for Cir if Dante is either unneeded or unavailable, as upon destruction, you will be able to defend yourself against two attacks instead of just one.
Fiendish Rhino Warrior: 1-2x Copies
One of the better non-archetype cards in a Burning Abyss deck, Rhino serves many purposes as both an extender and as protection against BA's own effects. In the strategy section we will cover how best to utilize this card both defensively and offensively.
Tour Guide From the Underworld: 1 Copy
Tour Guide serves as Burning Abyss' best follow up option post your initial set up. While a decent card to see in opening hand, it is best when searched by Scarm as a one card combo on your next turn
