I don't like the idea of limiting/semi-limiting one's own customs. If you find yourself having to do that for some reason, you're better off deleting the customs in question.
Conflagration-Mean Fox's effect can be shortened from:
While this card is face-up on the field: All "Conflagration"-Monsters gain 500 ATK and DEF. If a "Conflagration"-card effect deals damage to your opponent (except Conflagration-Mean Fox and Conflagration Kingdom): Deal 300 damage to your opponent.to:
"Conflagration" monsters gain 500 ATK/DEF. If a "Conflagration" card effect (except "Conflagration-Mean Fox" or "Conflagration Kingdom") inflicts damage to your opponent: Inflict 300 damage to them.There's no need to include "
While this card is face-up on the field" since those kinds of effects will already, by default, apply while the card that has the effect in question is face-up on the field. Also, "
ATK/DEF" means the same thing as "
ATK and DEF".
Remember not to include hyphens between an archetype and "
monsters" or anything.
Also, cards and effects don't "
deal" damage. They "
inflict" it.
Also, in some cases, you can replace "
your opponent" with just "
them" if the effect in question already listed that opponent earlier without referencing anyone else.
Kingdom of Conflagration's effect can be shortened from:
"Conflagration"-Monstrs you control gain 500 ATK and DEF. Once per turn, if a "Conflagration"-Card deals effect damage to your opponent: Deal 400 dmage to your opponent (this damage does not count for this cards effect). Once per turn: You can pay 500 LP, deal 500 damage to your opponent. (Both players can use this effect. This damage does not activate "Kingdom of Conflagration")to:
"Conflagration" monsters you control gain 500 ATK/DEF. Once per turn, if a "Conflagration" card inflicts battle or effect damage to your opponent: Inflict 400 damage to them. Once per turn: The turn player can pay 500 LP; they inflict 500 damage to their opponent.You misspelled "
monsters" and "
damage," and there's no need to specify that this effect doesn't/can't trigger its first effect from its second, since they're both once per turn and won't be able to loop with each other regardless.
Conflagration Seal of Sealing's effect can be shortened from:
When your opponent activates a spell- or trap: Pay 1000 life points: Negate the effect. The negated card remains on the field. During your opponents Standby Phase: Deal 300 damage to your opponent. If this card leaves the field; destroy the negated card. If the negated card is destroyed; send this card to the graveyard.to:
Activate by targeting 1 face-up card your opponent controls; negate its effects. When this card leaves the field, destroy that card. When that card is destroyed, destroy this card. Once per opponent's turn: You can inflict 300 damage to them.Having an effect that forces the negated card to remain on the field will only create confusion, so it should just negate the effects of things and let them stay on or leave the field depending on what they do by default.
Burning Heart's effect can be buffed from:
Each time your opponent takes damage by the effect of a "Conflagration"-Card: Gain life points in the amount of the damageto:
If your opponent takes damage: Gain that much LP, and if you do, you can destroy 1 "Conflagration" monster you control and 1 card they control.This effect is perfectly fine being completely generic and not restricted to any archetype, as life point gain cards are usually terrible by default.
Conflagration-Soldier's effect can be buffed from:
During your Standby Phase: Deal 300 damage to your opponent. If this card is destroyed by battle and send to the graveyard: You can special summon 1 "Conflagration-Soldier" from your Deck.to:
During your Standby Phase: Inflict 300 damage to your opponent. If this card is sent to the GY: You can Special Summon 1 "Conflagration-Soldier" from your hand or Deck. You cannot Special Summon the turn you activate this effect, except "Conflagration" monsters.It's "
sent to the GY" with a T, not "
send to the graveyard" with a D, since you're using the past, not present tense. Also, requiring it to be destroyed by battle first makes it too slow, so it should be able to trigger off of being sent from the graveyard by any means, as long as that effect can't be abused outside its archetype.
Also, we now say "
GY" not "
graveyard".
https://yugipedia.com/wiki/Problem-Solving_Card_TextConflagration-Defender's effect can be shortened from:
During your Standby Phase: Deal 100 damage to your opponent. This card cant be destroyed by card effects. The battle position of this card cannot be changed by card effects.to:
Your cards cannot be destroyed by effects. During your Standby Phase: Inflict 100 damage to your opponent.The protection effect should be listed first since it's the most important part of the effect opponents need to see, and it's better off, in my opinion, protecting all your cards instead of just itself, at the cost of no longer preventing battle position changes.
Conflagration-zombie's effect can be buffed from:
Once per turn: If this card is destroyed by battle and sent to the graveyard: Pay 300 life points then summon it in face-up attack position in your next Standby Phase. During each Standby Phase: Deal 300 damage to your opponent.to:
During your Standby Phase, if this card is in your hand or GY: You can pay 300 LP; Special Summon this card in Attack Position. Another "Conflagration" card must be on your field or GY to activate and resolve this effect. You can only use this effect of "Conflagration-zombie" up to thrice per turn. During each Standby Phase: Inflict 300 damage to your opponent.So its like
Treeborn Frog, but doesn't require that you control no spells/traps and instead is limited to 3 times per turn.
Ignas, King of Conflagration's effect can be buffed from:
This card is unaffected by trap cards. If this card attacks a monster, negate the effect of the attacked monster. If this card destroys a monster deal 800 damage to your opponent. During your Standby Phase: Deal 400 damage to your opponent. You can send this card and one other "Conflagration"-Monster to the graveyard to summon "Ignatia, Queen of Conflagration" from your extra deck.to:
Unaffected by Trap effects. If this card attacks a face-up monster, negate that monster's effects until the end of the Damage Step. If this card attacks directly or a Set monster, your opponent cannot activate cards or effects until the end of the Damage Step. If this card destroys a monster by battle: Inflict 800 damage to your opponent. During your Standby Phase: Inflict 400 damage to your opponent. You can send 2 "Conflagration" monsters you control to the GY; Special Summon 1 "Ignatia, Queen of Conflagration" from your Extra Deck.Extra Deck is always capitalized, and you don't need to start the first effect with "
this card is," as plenty of monster's say just "
Unaffected by [X] effects" without including "
this card is" there.
Conflagration-Ghost's effect can be shortened from:
During you Standby Phase: Deal 200 damage to your opponent. Once per turn; in your main phase: Place 1 "Burn"-Counter on a face-up Monster your opponent controls. For each "Burn"-Counter on a Monster its DEF are reduced about 500. If a Monster with 0 DEF has 1 or more "Burn"-Counter on it: Destroy it and deal 500 damage to your opponent.to:
During your Standby Phase: Inflict 200 damage to your opponent. Once per turn (Quick Effect): You can target 1 face-up monster; change its DEF to 0 until the end of this turn. Up to twice per turn, when a monster's DEF gets changed to 0: You can target 1 monster with 0 DEF; destroy it, and if you do, inflict 500 damage to your opponent.Recommend deleting Conflagration Ritual of Mindsealing since it's too similar to the previous continuous trap with the change I suggested, and because the archetype already seems to have enough main deck cards.
Also recommend deleting the rest of the archetype's spells since much better non-archetype alternatives already exist, like
Monster Reborn.
Ignatia, Queen of Conflagration's effect can be shortened from:
This card can only be summoned by "Ignas, King of Conflagration". When this card is summoned: Deal 200 damage to your opponent for every "Conflagration"-Monster on the field and in your graveyard. During your End Phase: Deal 800 damage to your opponent. This card is unaffected by card effects that would destroy itto:
Must be Special Summoned by "Ignas, King of Conflagration". Unaffected by effects that include a card destroying effect. If this card is Summoned: Inflict 200 damage to your opponent for each "Conflagration" monster on your field and GY. During your End Phase: Inflict 800 damage to your opponent.Summoned, and
Special Summoned, are always capitalized, also its shorter to say "
Must be Special Summoned by" than "
This card can only be summoned by". Also, the unaffected effect should be closer to the top so the opponent is less likely to miss it, since its rather important for them to see.
Now, for an archetype that wants to summon fusion and synchro monsters, it seems to have a hard time doing either, as it has only 1 card that can bring out its fusion, and only 1 card that can bring out its synchros, neither of which are easy to bring out themselves.
I recommend changing all the archetype's monster's levels to even numbers, so, change Conflagration-Ghost's level from 3 to 2, change Ignas, King of Conflagration's level from 7 to 6 or 8, and change Ember, Highpriestess of Conflagration's level from 5 to 6.
Then, make these changes to the synchro monsters:
Flareo, Magician of Conflagration1 Tuner + 1+ non-Tuner "Conflagration" monsters
For this card's Synchro Summon, you can treat 1 "Conflagration" monster you control as a Tuner. During your Standby Phase: Inflict 500 damage to your opponent. Once per turn: You can discard 1 card or pay 600 LP; destroy 1 card your opponent controls.Also recommend shortening
Flareon to
Flareo or something so it's not an awkward reference to the pokemon
Flareon.
Kuzarzu, Demongod of Conflagration1 Tuner + 1+ non-Tuner "Conflagration" monsters
For this card's Synchro Summon, you can treat 1 "Conflagration" monster you control as a Tuner. During your Standby Phase: Inflict 500 damage to your opponent. Once per turn: You can banish up to 3 cards from any GY(s) and/or your opponent's face-up Extra Deck; inflict 400 damage to them for each banished. If this card leaves the field: Inflict 800 damage to your opponent.Ember, Highpriestess of Conflagration1 Tuner + 1+ non-Tuner "Conflagration" monsters
For this card's Synchro Summon, you can treat 1 "Conflagration" monster you control as a Tuner. During your Standby Phase: Both players gain 600 LP. During the Standby Phase: You can banish this card from your field or GY; activate 1 "Burning" Continuous Spell from your Deck or GY, and if you do, you can shuffle any number of cards from your field and/or GY into the Deck, except that card.Niran, Warhorse of Conflagration1 Tuner + 1+ non-Tuner "Conflagration" monsters
For this card's Synchro Summon, you can treat 1 "Conflagration" monster you control as a Tuner. Once per turn, you can either: Target 1 monster you control; equip this card to that target, OR: Unequip this card and Special Summon it. A monster equipped with this card gains 500 ATK/DEF, also if it would be destroyed by battle or effect, destroy this card instead. Up to thrice per turn, if a monster activates its effect while this card is equipped to it: Inflict 800 damage to your opponent.
