Answers taken from the YGO! TCG Website: http://www.yugioh-card.com/en/gameplay/faqs/basicgameplay/ ...If a Special Summon-only monster is successfully Special Summoned to the field, using the proper method, and is then sent from the field to the Graveyard, you may use "Monster Reborn", etc. to revive the monster back to the field, and you do not have to use the proper method again. (For example, if you Special Summon "Aqua Spirit" by removing 1 WATER monster in your Graveyard from play, and "Aqua Spirit" is then destroyed and sent to your Graveyard, you may use "Monster Reborn" on "Aqua Spirit" without having to remove another WATER monster in your Graveyard from play.) However, if a Special Summon-only monster is placed in your Graveyard because it was discarded from your hand, or some other method that did not involve the monster being Special Summoned to the field using the proper method, you cannot use "Monster Reborn", etc. on the monster. ---- No, you will never be able to Special Summon "Armed Dragon LV7" [or "Uria, Loard of Saering Flames"] with "Monster Reborn" because "Armed Dragon LV7" [and "Uria, Loard of Saering Flames"] is a monster that can only be Special Summoned by the method described in its text. These monsters can be identified by the text "This card cannot be Normal Summoned or Set. This card cannot be Special Summoned except by …". This means that the method described after the "except by" is the only way that monster can ever be Summoned. This prevents it from being Special Summoned from the Graveyard with "Monster Reborn", "Call of the Haunted", or any other effect, even if it was properly Summoned by its own effect first. Some earlier prints of cards do not have the "This card cannot be Special Summoned except by…" text, but are still included in this category of monsters. These cards include "Exodia Necross", "Berserk Dragon", and "Mirage Knight".
