Burning Abyss, or BA for short, is an archetype of Fiend-Type monsters that are very xenophobic, as they destroy themselves if you control a non-BA monster, unless they are negated, such as via Tour Guide, or are protected, such as via Cherubini or Rhino Warrior, and don't have any really good archetypal spells or traps, and have very powerful monster effects. So you know what that means, we're shoving in Sekka's Light, baby!
For the decklist, we have a BA package of 3x Cir, 2x Alich, 1x Farfa, 3x Graff, 3x Scarm, 1x Beatrice, 2x Dante, and 2x Cherubini, my preferred Handtrap lineup of 2x Nibiru, 3x Ash Blossom, 2x Ghost Belle, 3x Maxx C, and 2x Veiler, 2x Fairy Tail - Snow, 3x Rhino Warrior, 3x Tsuchinoko, 3x Tour Guide, 2x Jackalope and 3x Sekka's Light, and for the rest of the Extra Deck, we have 1x Hot Red Dragon Archfiend Abyss, 1x Borreload Savage, 1x Chaos Ruler, 1x Zeus, 1x Downerd, 1x Leviair, 1x Gossip Shadow, 1x Underworld Goddess, 1x Accesscode, and 1x Knightmare Unicorn.
