You can Normal Summon this card while you control Red Daemon's Dragon, Special Summon a second copy, use the Special Summon effect targeting RDD to gain 3000 LP, then Double Tune both Red Resonators with RDD to bring out Scar-Red Nova Dragon.
Nice.
It's weird how slow they are with releasing the upgraded signer dragons. We only recently got Red Dragon Archfiend/Assault Mode and 5Ds has been out for over 15 months.
Speaking of Nova, OCG just revealed a new version called Scar-Red Supernova Dragon that requires 3 (THREE) Tuners and 1 non-Tuner Synchro monster as material.
