Is This Deck Meta?
This deck was never meta since it lacks the ability to destroy the enemy backrow and is not able to play through card effect negatations. The Red Dragon Archfiend archtype used to be a very simple archtype consisting of attacking with attack power synchro boss monsters and using spell cards to gain a field advantage or to help make the attack successful. The Red Dragon Archfiend monsters are a unique archtype, where they use two types of monster: non-tuner monsters and tuner monster. In additon, they use to specialize in bringing out level 8 synchro monster and then synchro climb into their level 9, or level 10, or level 12 synchro monsters until the new additons of Red Rising Dragon, Crimson Resonator, and Red SuperNova Dragon.
Playing Style
Compared to the more passive "Stardust Dragon", which specializes in negating card effects and overall defense, "Red Dragon Archfiends" have a more smash mouth strategy, revolving around destruction, battle oriented effects, ATK increasing, Special Summoning Tuner monsters and negation, resulting on boards filled with Synchro monsters of over 3000 ATK that can quickly overwhelm the opponent. The "Red Dragons" are designed to have synergy with the "Resonator" archetype, many of which have Special Summon conditions to facilitate Synchro Summons and, furthermore, Double Tuning.
To start off, the level 8 "Red Dragon Archfiends" focus on simple destruction of the enemy's monsters under certain conditions, in order to quickly gain or recover field advantage over the opponent and push them into a corner, then use them as bridges to the more powerful evolved forms. The original "Red Dragon Archfiend" destroys Defense Position monsters, "Hot Red Dragon Archfiend" destroys all monsters in Attack Position besides itself while "Scarlight Red Dragon Archfiend" destroys special summoned monsters weaker than itself.
