you are all wrong horus the black flame dragon lv8 is the strongest stops all spells combined with royal deree unstopable
How are we all wrong when playing "favorites"?
Not that yours is much better a choice compared to anyone else's, since your claim of it being invincible is false. In fact, the combination of Royal Decree is highly flawed without Destiny Hero Plasma, who is the most important of the three-card combination.
Chaos Sorcerer, D.D. Warrior Lady, D.D. Assailant, and Caius the Shadow Monarch can easily remove it.
Colossal Fighter in mid to late game, and any LIGHT monster with Honest in the player's hand can easily run over it.
Exiled Force, Old Vindictive Magician, Gladiator Beast Murmillo, Celestia Lightsworn Angel, Judgment Dragon, Dark Armed Dragon, Man-Eater Bug, and Ryko Lightsworn Hunter can easily destroy it.
Neo-Spacian Grand Mole, Penguin Soldier, and Gravekeeper's Guard can easily bounce it back.
Raiza the Storm Monarch can easily spin it.
We're all wrong? You're wrong. So very, very wrong.
