If a "Red Dragon Archfiend" monster you control battles, during damage calculation: Make that monster you control unable to be destroyed by that battle, and if you do, Special Summon this card as a Normal Monster (Fiend-Type/Tuner/FIRE/Level 1/ATK 0/DEF 0). (This card is also still a Trap Card.)
Special Summons itself from your Spell & Trap Card Zone
Treated as a Normal Monster / Treats itself as a Tuner monster
Cannot be destroyed by battle
1. Negates Red Dragon Archfiend destruction once
2. Summons as a lvl 1 tuner after that
3. Useful for Double Tuning if they add Red Nova Dragon
1. Only prevents Red Dragon Archfiend destruction by battle.
2. This card effect can only be used once, since it summons itself if the first effect goes through
3. 0 ATK & DEF makes it extremely vulnerable
Even activating this card during opponent's turn has its weakness: unless your opponent cannot attack anymore, this card would surely be gone at the end of the turn. That's where Urgent Tuning would serve a use.
Useful card if they add Red Nova Dragon/Tyrant Red Dragon Archfiend/Hot Red Dragon Archfiend King Calamity to the game.
