It comes in the Machina Mayhem structure deck.
Proto-Cyber Dragon is from Shadow of Infinity, but is also in Duelist Pack 4 and Dark Revelation Vol 4.
The booster packs that have "Cyber Dragon" are Cybernetic Revolution, Duelist Pack 4: Zane Truesdale, Gold Series, Ra Yellow Mega-Pack, and Battle Pack: Epic Dawn.
I got this from a Zane Truesdale Duelist Pack, it doesn't show how many of one card he has, but its a start. This is light and dark Zanes deck I think.

to get cyber end dragon you need to waste alot of money. In the card series which has cyber end dragon on the cover of pack. Don`t only buy one pack you have to buy the big box set which has thirty packs of the yu gi oh series. It will be a easier way to get cyber end dragon.
Cyber End Dragon was found in Cybernetic Revolution, Duelist Pack 4: Zane Truesdale, and Dark Revelation 4. It was also a promo card in the Strike of Neos special edition box, and a promo included with a Cyber End Dragon toy from Mattel.
The Fantasy pack! :)
The card Dragon Master Knight came in the booster pack "Duelist Pack: Kaiba".
"Rainbow Dragon" was released in the TCG booster pack Tactical Evolution.
No, it does not come in any booster pack. It is only available in Structure Deck 1 - Dragon's Roar.
Zane Truesdale and Cybernetic Revolution, you could look at cyber dragons picture and compare it to other booster packs.Duh.
You have to do extremely good with whoever has Cyber End Dragon in Yu-Gi-Oh GX and then a pack will become available with the cards he uses. I might be thinking of a different game, but try it! (I think Zane Truesdale has it)
