Auto decks are decks that are mainly made to be used with the "Auto-Duel" function. The reason why people often want to go with Auto-Duel is simply because it is done much faster than manual play, since it is fast forwarded and easy to use with just one button. Keep in mind that win rates for auto decks vary depending on what level of Standard Duelists you are going against.
Some decks are made to have a high chance of winning and ends fast. This is good if you ever want to level a character quickly or buy a "Boosted Duel Orb" from the shop. With only an hour of infinite standard duelist spawns, winning the duels quickly can earn you a lot of exp, levelling a character up quite fast.
2. High score for items
The other type of decks are made to get a high score with auto duels. These decks might not have a consistently high win rate compared to the ones made to win, but they can often give up to 3000 or 4000 easily by using auto duel from the start. Earning a lot of points from the Duel Assessment will give more rewards like golds, stones/orbs, and most importantly, the standard gate keys and the colored ones used to farm Legendary Duelists.
How to make an Auto Deck
3 things you should know to build a good auto deck:
1. AI Interaction You will need to get a good understanding of how the game's AI work, which can change from time to time. Press the auto-duel and see how they interact with some of the cards. It's recommended to keep things simple by using cards like Reinforcements, Metalmorph or Riryoku.
3. Check the Duel Assessment page To make an auto deck that gives a lot of points, you will need to understand first what are the things you need to do to get a lot of points. Take a look at the Duel Assessment section. Make an auto deck that can tribute, fusion or ritual to get more points, destroy 5 enemy monsters or be able to summon Meteor B. Dragon to deal over 3,000 damage. Being able to end the duel fast from either turn 1-4 can also earn the quick victory bonus.
AI cannot activate skills manually. That means you will set a skill activated automatically to your auto deck.
Example of skills work in auto duel
Power of Dark
LP Boost skills
Example of skills AI cannot use
As mentioned above, skills activated manually cannot be used in Auto Duel since AI do not activate them. You should not build auto duel decks with those skills. Here are examples of such skills.
Change the "Power Usage" from the in-game settings and set it to max to increase the game's speed. It will make it look more fluent and smoother, but it will of course drain more of your battery to run it.
More examples of auto decks
In the game, you can also find a lot of people sharing their auto decks that work well for them and might be good for anyone that have those cards. Visit the deck board from the right most building to see what they use, and use the copy feature to copy the recipe to your characters. Check for the highly rated decks and see their deck names, if they have "オート" written on them, it means that they are an auto deck.
Got any Auto Deck? Feel free to share them in the comments below by attaching a picture of your deck, be sure to post which level of Standard Duelist it works well against too!
UAGG won't work with "balance" cause there have to be at least 6 of every type of cards... This build got only 5
The other Decks here won't work exactly right at this time (June 2018) cause of many nerfed and forbidden cards
Easiest way to find cards from images yiu dont know. Go to card catalouge. You can see its a 4 star monster. And the type is at the bottom. Then find the same image. Then it also tells you how to get them. These are all easy cards. This is cheap imo
Lot of people here complaining on how dumb AI is. If they upgrade AI then the farming will also gets harder that's why its ok if they're dumb you just need to make your Auto duel deck basic so AI can handle it.
Just what another comment said, Never Auto Duel coz AI sucks. More than 20 times I do Auto Duel with standard beater and increasing Atk cards and destroyer monster cards. For example when my AI have 1 1900 atk monster and have Super Rush in the hand he activates it even the opp. Monster is set. Then he crush it but on the next turn opp. Activates equip spell to increase Atk and destroy my monster which has lower atk and AI already activated Super Rush and no backrow then I lose. It's awful
