Card Rulings:Horus the Black Flame Dragon LV6


 * The "you" in "on your side of the field" is the current controller's field, so as long as "Horus the Black Flame Dragon LV6" is face-up, it is always "face-up on your side of the field".


 * You cannot Tribute "Horus the Black Flame Dragon LV6" for "Ectoplasmer's" effect because it is not a cost, it is a Tribute when you resolve "Ectoplasmer's" effect, and "Horus the Black Flame Dragon LV6" is not affected by Spell Cards' effects.


 * If "Horus the Black Flame Dragon LV6" is equipped with "Metallizing Parasite - Lunatite", and would be destroyed as a result of battle, "Metallizing Parasite - Lunatite" is destroyed instead (this is not negated by "Horus the Black Flame Dragon LV6's" effect).


 * If "Horus the Black Flame Dragon LV6" is the only monster on the field, you can activate a Spell Card that targets, but its effect will be negated because "Horus the Black Flame Dragon LV6" would be the only valid target and it is unaffected by Spell Cards.


 * You can activate "Level Up!" and send "Horus the Black Flame Dragon LV6" to the Graveyard to Special Summon "Horus the Black Flame Dragon LV8" because sending 1 monster to the Graveyard is a cost for "Level Up!" and if a card is unaffected by Spell Cards, that only refers to effects, not to costs.


 * If a level monster fulfills its condition to Special Summon the next-highest level (for example, if "Armed Dragon LV5" destroys a monster as a result of battle), and the level monster is then flipped face-down, or removed from play permanently, or sent to the Graveyard and then Special Summoned from the Graveyard, then its condition is reset and it is no longer considered to have met the condition to Level Up to the next level.
