If this card attacks an opponent's monster, it gains 300 ATK during the Damage Step only. Once per turn: You can reveal 1 Spell Card in your hand; this card's name becomes "Cyber Dragon" until the End Phase. This card's name becomes "Cyber Dragon" while it is in the Graveyard.
This card is able to Special Summon Cyber Barrier Dragon from your hand or deck, by tributing your Cyber Dragon Zwei (after it has been named “Cyber Dragon”). If you have Cyber Dragon Zwei in your Graveyard, you can use Cyber Repair Plant to add another LIGHT machine type monster to your hand, or you can also shuffle Cyber Dragon Zwei back to the Deck from the Graveyard. By using Photon Generator Unit, you can use Cyber Dragon Zwei (after it has been named “Cyber Dragon”) together with Proto-Cyber Dragon, tribute them to Special Summon Cyber Laser Dragon from your hand, Deck, or Graveyard
One of the strengths of Cybernetic archetypes is that they can also use Machine-type support cards. Pulse Mines is able to switch all your opponent’s monsters into Defense position for that turn, Rare Metalmorph is able to negate 1 Spell that targets your Machine-type monsters and grants additional ATK power. Sergeant Electro functions to pin down your opponent’s face-down Spell/Traps, and can also be used as 1 of the Fusion materials for Chimeratech Overdragon.
This is one of the most versatile Cybernetics archetype monster because it has a decent attack power and can substitute for actions that requires “Cyber Dragon” in order to perform.
This card can also count as 1 of the Fusion materials for Chimeratech Overdragon, by playing its role as either “Cyber Dragon” or 1 of the Machine-type Fusion materials.
Last Gamble Can be used in your Main Phase, starting from the fifth turn. Upon activation, reduces your LP to 100 and discards 2 cards from your hand. You roll a die and draw that number of cards. This skill can only be used once per Duel.
Master of Fusion Can be used each time your Life Points decrase by 1800. In the Draw Phase, instead of doing a normal draw, one Polymerization Spell Card, from outside of your Deck, is added to your hand.
"kaiser is emperor in English" Actually "Kaiser" is German for "Emperor", same as "Tzar" is Russian for Emperor, both coming from the word Caesar, which was the honorific used to refer to Emperors in the Roman era starting with Augustus (Julius Caesar himself never got to be emperor). A quick Google Search... ;)
Why are you even complaining? I've farmed it a crazy amount of time to only get 1 Cyber Repair... I've gotten like 5 Zwei, 9 Chimeratech, 7 Fusion support, 5 Cyber Laser Dragons, and an uncountable amount of Barrier Dragons and other R cards...
