No you cannot. When a monster says it 'cannot be special summoned except by..' it means that's the only way it can ever reach the field. Five-Headed Dragon can't be special summoned, except by Fusion Summoning it. Even if you fusion summon it and it is destroyed, it can't be brought back to the field by cards like Call of the Haunted, or Red-Eyes Darkness Metal Dragon.
Light and Darkness Dragon's first line of text says that it cannot be special summoned. Therefore when it is destroyed and its last effect triggers, it cannot choose itself.
No, only the player who activated Flute of Summoning Dragon can special summon the dragons through its effect.
Seeing how they are supposed to work hand in hand as a great combination, but seeing how the question is to see which is better, it is Red-Eyes Darkness Metal Dragon, not because of ATK and DEF, but because of how easy it is to Summon him, along with an effect to Summon more powerful Dragons as well. You can Summon Poki Draco and Banish it to Summon REDMD in an instant. While Prime Material has to be either Special Summoned by another method, or plain Tribute Summon it, which is usually slower.
Cards that can 'only be Special Summoned by', or 'cannot be Special Summoned except by' can only ever reach the field initially by that listed method.Flute of Summoning Dragon can never summon Rainbow Dragon. Even if the conditions are right, that's something that allows you to special summon it (at the same timing as a Normal Summon in your turn), not any external effect.Cards that state "...can only be Special Summoned by..." can be Special Summoned, for example, from the Graveyard after its initial Special Summon (by its own effect) is successful. For example, you Special Summon The Rock Spirit from your Hand by removing from play one Rock-Type monster in your Graveyard. Your opponent then somehow manages to destroy The Rock Spirit. Because it was successfully Special Summoned by its own effect, The Rock Spirit is now eligible to be Special Summoned from the Graveyard via a effect such as Call of the Haunted.
Stardust Dragon will be able to use its effect to negate a card. However, it will not be able to Special Summon itself from the Graveyard. This is because it was not properly Synchro Summoned first; therefore, it is not eligible to be Special Summoned from the Graveyard.The effect of Starlight Road does not state that the Special Summon is treated as a Synchro Summon. It does not properly Synchro Summon Stardust Dragon.For confirmation on this ruling, click on the "Related Link" below.
You can only activate and Special Summon "Red Eyes Darkness Metal Dragon" with this effect from your hand.
Red-Eyes Darkness Metal Dragon's own summon does not use the chain. Because nothing is activating, there is nothing for Divine Wrath to chain to - Divine Wrath negates 'activations' of monster effects. Red-Eyes Darkness Metal Dragon's effect to special summon other dragons though is an Ignition Effect, which is a form of activated effect. This can be negated using Divine Wrath.
Light and Darkness Dragon's first line of text says that it cannot be special summoned. Therefore when it is destroyed and its last effect triggers, it cannot choose itself.
If you special summon a Totem Dragon, and then tribute it for Red Eyes Darkness Metal Dragon, then Totem Dragon goes straight from field to the removed from play zone. It never hits the graveyard, and is therefore never a valid target for Red Eyes Darkness Metal Dragon's dragon summoning effect.
In theory, yes. Light and Darkness Dragon's negation effect does not target, it could potentially be chained to Blue-Eyes Shining Dragon's Quick Effect. However becase Light and Darkness Dragon's effect is mandatory, in practice it will actually chain to the initial targeting effect, the one Blue-Eyes Shining Dragon was going to use its effect against.
Red-Eyes Darkness Metal Dragon's effect is an Ignition Effect so cannot be chained to anything.
No. The text has been changed but the effect remains the same, first it was a 'cannot be special summoned except by..' monster, which means only the listed method could ever be used, it was not the kind that could be brought back assuming you summoned it properly first. Now it says "Must be summoned by....cannot be summoned in any other way", again, it doesn't matter if you properly summoned it, it can't be summoned back from the graveyard.
No, Light and Darkness Dragon's negation effect is a Quick Effect which is spell speed 2, so it cannot chain to a Counter Trap which is spell speed 3.
Unless specifically stated otherwise, a monster's summoning requirements are for when it is in your hand. Plaguespreader Zombie is an example of a monster that can be special summoned by its own effect while it is in a different zone (graveyard in this case). Red-Eyes Darkness Metal Dragon has no such text, so the listed special summoning method can only be used while it is in hand.
No part of Winged Dragon of Ra's effect stops you from Special Summoning while you have him out on the field.
No, the only time a monster can special summon itself from the graveyard, is if it specifically says so - Plaguespreader Zombie for example. If it doesn't specify, then the default zone for special summoning is from the hand.
No, no card's effect can be activated while it is in deck.
