Self-burning

[Zyzzyzus]

Of course it's another fire archetype. The ___ Phlogist monsters are the main members, they are supposed to be seraphim in violet flames (can't find art of it). The 3 Phlox monsters were judged by the Phlogists in the afterlife, and forced into service since they failed their purpose in their original forms (Legendary Fiend is a legend only in name, Zoa's full potential was quite lacking, and DIabolos was Demoted to Dark King of the Abyss, supposedly.)


Conflagration
Continuous Trap Card
When this card is activated, place it in the Field Spell Card Zone (and destroy any card that currently occupies a Field Spell Card Zone on either side of the field.) As long as this card remains face-up on the field, you can activate a Trap Card whose effect treats itself as a monster during the turn that it is Set. Once per turn, if a "Phlogist" or "Phlox" monster in your hand or Graveyard can be Special Summoned when you take damage, you can Special Summon it when you inflict the amount of damage listed in the card text to your opponent.

The Flame of Greed
Quickplay Spell Card
You can only activate this card during your opponent's Standby Phase, while they control at least 2 monsters. During this turn, whenever a monster is Summoned or sent to the Graveyard, you take 800 damage. During the End Phase of the turn that this card is activated, draw 3 cards.

The Flame of Hatred
Quickplay Spell Card
This turn, whenever a monster is Summoned or declares an attack, place 1 Flame Counter on that card, and you take 600 damage. During the End Phase of the turn that this card is activated, destroy all monsters that has a Flame Counter(s) on it.

The Flame of Delusion
Quickplay Spell Card
Tribute 1 Level 7 or higher FIRE-Attribute monster you control. This turn, all damage you take instead increases your Life Points by the same amount (but it is still treated as damage). During the End Phase of the turn that this card is activated, it is placed on the top of your Deck.

The Immortal of Flame
Continuous Trap Card
When this card is activated, Special Summon it as an Effect Monster Card (Fairy-Type/FIRE/Level 4/ATK 1400/DEF 2100). (This card is still treated as a Trap Card.) You can Tribute this card to Special Summon 1 "Phlogistic" monster from your Deck. During the end of the Battle Phase of the turn that this effect is activated, you can Set this card from your Graveyard in a Spell & Trap Card Zone, and take 800 damage.

Archfiend of the Blue Flame
Continuous Trap Card
When this card is activated, Special Summon it as an Effect Monster Card (Fiend-Type/FIRE/Level 4/ATK 1700/DEF 600). (This card is still treated as a Trap Card.) When a "Phlogist" monster you control would be targeted by a card effect, you can negate that effect and destroy it. Each time this effect is activated, you take 600 damage. During either player's turn, you can Tribute this card to negate the activation of a monster's effect and banish it, then you take 1000 damage.

The Exalted Phlogist
Level 1
FIRE
Fairy/Effect
When this card is Summoned, you can add 1 "Phlox" monster from your Deck to your hand. This card cannot be destroyed by battle. When this card would be targeted or destroyed by a card effect, you can send 1 "Phlogist" or "Phlox" monster from your hand or Deck to the Graveyard, except "The Exalted Phlogist": This card is unaffected by that card effect, and gains 700 ATK and DEF. If you activate this effect, you take damage equal to the Level of the discarded monster x 300.

When this card is Summoned, you can add up to 2 "Phlox" monsters from your Deck to your hand. When a monster effect is activated, you can target that monster and negate its effect(s) and take damage equal to the Level of the target x 400 (only 1 monster at a time can be targeted). Monsters with the same name as the target cannot activate their effects as long as this card remains face-up on the field.
300/350

The Ardent Phlogist
Level 3
FIRE
Fairy/Tuner
You can Special Summon this card from your hand when a "Phlogist" monster you control is attacked. If this card is Summoned this way, take control of the attacking monster, and until the End Phase, any damage inflicted to either player increases their Life Points by the same amount instead (it is still treated as damage).

1000/1650
*Another version of Hiita the Fire Charmer that allied with the Phlogists. I'm not too sure whether or not Gishki Ariel and Winda, Priestess of Gusto are actually Eria and Wynn or not, but it's the same idea.
