Will the Yu-Gi-Oh card Skill Drain work on Extreme Jade God Rainbow Dragon and Elemental Hero Captain Gold?

Answer 1

Firstly, "Extreme Jade God Rainbow Dragon" is just Rainbow Dragon; only the Japanese names of Rainbow Dragonand Rainbow Dark Dragonincludes the words "Ultimate Gem God".

As for Elemental Hero Captain Gold and Skill Drain, the answer is yes, his effect will be negated and Captain Goldwill not be destroyed if Skyscraperis not face-up on the field. But Skill Drainwill not negate the first effect of Captain Goldthat lets you discard it to find a Skyscraper in your deck.

Skill Drainalso negates the effect of Rainbow Dragon, but it's a bit more complicated. Rainbow Dragoncan still be Special Summoned from your hand if you've met the conditions to do so. Now, since Skill Drainonly negates the effects of monsters on the field, but does not prevent you from activating them, Rainbow Dragoncan still activate his effects the turn after it was summoned. Both of this card's effects have a costand the cost to activate a card's effect must be paid before it resolves or gets negated.

Simply put, if you activate the effect ofRainbow Dragonto increase its ATK, you must send "Crystal Beast" monsters on your side of the field to the Graveyard first. If you or your opponent then chains this effect with Skill Drainor Skill Drain was already face-up on the field, your Rainbow Dragonwill not gain any ATK. Similarly, if you activate the card's second effect to return all cards on the field to their owner's deck, you must banish all "Crystal Beast" cards in your Graveyard even if the effect is negated.
