The rarest card that can be pulled from a booster pack would be any one of the 15 Secret Rare cards from Gladiator's Assault. It was the set with the most secret rare cards, meaning statistically to pull any single named secret rare, you would have to buy more boxes than for any other set which had less secret rare cards in.

The red one!
It comes in packs of Stardust Overdrive.
Of course it does. And it even includes: -1 token pack -2 "the duelist genesis" booster packs -2 "phantom darkness" booster packs -1 "light of destruction" booster pack Hope it helped and good luck with getting good cards out of it (which you probably will)!
you got them both from booster packs? Dude you are sooo lucky
It's about $40-50 according to YugiCo.com. http://yugico.com/yugioh-cards/booster-packs/PTDN-Phantom_Darkness/PTDN-EN081-Darklord_Zerato/
You get it by defeating people but it is completely random eg Powertool Dragon you get from Leo and Stardust dragon from yusei
