"There's one in this for Ultimate Offering" Deck 2012

Playing

If you can leave Gadget, you can Xyz on the next turn, so it is important to stop the opponent's counterattack as efficiently as possible.
Therefore, it is important to use not only Naraku and Warning, but also free chains such as 《Compulsory Evacuation Device》and Sambre.
As for Xyz destination options, if you have time to spare, take Ads with Gear Gigant, and if you have Sacred Time or Laval, Roach,
One of the ways to play is to match your opponent's girlfriend's Deck with Mae Stroke if it's Hirobi or Lagia.
4 Xyz has a variety of options, so it's difficult to get the correct answer, but if you can make a solid choice at the key points, it's a pretty powerful weapon.
Basically, fortresses are not forced to expand. Save as much cards as possible in your hand for when you go to decide or when a monster you can't break through appears.
However, if you are sure that there is no metabi opponent, torrent funeral, or black hole, there are times when you can deploy it.
Even the presence of Fortress puts a lot of pressure on the opponent, and it also acts as a restraint.
In the current environment, summoning reaction trap > attack reaction trap, and there are many decks of him that take a lot of time to remove Fortress once it appears.
There is no correct timing for summoning Fortress, but creating a situation where the opponent cannot counterattack is one of the roles of Fortress, and it is also a highlight of playing.
...However, the above information is about the previous environment, and in the current environment, most of his decks are either imprisoned or mirafo, so you can't feel relieved even after you can deploy.
Also, with the addition of 4 Xyz, including Gear Gigant, you can fight stably even without 《Ultimate Offering》.
Therefore, there is no need to draw cards such as Car D, and Ultimate Offering wins if it passes. You should keep it in mind.
It's a good idea to improve your playing so that you can win even without 《Ultimate Offering》.

Strength

《Ultimate Offering》basically doesn't work
It depends on your luck that day.

Weakness

It's vulnerable to handicap cards like 《Mind Crush》and 《Dragged Down into the Grave》.
After that, it is also weak against 《Deck Devastation Virus》.
I hate Dark World...

Customize

Trap can be changed as you like
If you can't get extra G, I think you can fight well without it.
Everyone, let's accumulate 《Macro Cosmos》against Dark World and Mermail on your side! !
Maybe something like 《Dimensional Prison》will become a meta for Dark World and HERO beats? kana?
