There are seven different decks based on the SOUL attributes described in the game of Undertale. Each deck has its own unique ability as well as Effect Cards to go with it. Deck specific cards can be identified by the matching colour of their name at the top of the card.

In order to complete a deck one must have exactly 25 cards in it. This can be achieved by clicking on Cards, then Decks in the main menu and then clicking on the cards you wish to add to your deck (more info here). If you are new to the game, it is recommended to have a Draw artifact or an additional draw engine. You can also counter a lot of cards with Scarf Mouse or Nacarat Jester (who can Silence). Echo Flower is also a really good card for beginners.

* Determination
* Patience
* Bravery
* Integrity
* Perseverance
* Kindness
* Justice
### **Determination**

#### **Ability: The first time you would die, set your HP to 5 instead. Start the game with the save artifact. (save artifact= When 7 monsters die (except Lost Souls), summon the next Lost Soul at 1/1, or 2/2 stats if you have 10 or less HP. Lost Soul order: Lost Alphys > Lost Papyrus > Lost Undyne > Lost Toriel > Lost Asgore > Lost Sans > Loop back to Lost Alphys.)**

This deck is suggested for experienced players. The deck is based around your dustpile and making use of your lost souls, as many spells in this deck either revive monsters or work towards using the effects of lost souls. Determination is the literal definition between life and death, you get a second chance should you fall (any excess dmg dealt on the 1st death will be negated) Determination players base their decks on trying to summon more monsters to make more uses of the lost souls as Last dream uses every single Lost soul effect that has been played up to that point, or Resurrection, to increase the counter further. These decks are strong against Bravery zoos, and Justice, as Bravery summons more weaker monsters and Justice triggers the lost soul effects quicker. Weaker against Integrity and Patience, as Integrity saves g for single monsters and Patience can prevent lost souls from spawning

This deck's Spells are Another Chance, Control Wire,Faded Memory,Call of the Grave, Hyper Goner, Knife, Last Dream, Resurrection, Same Fate, Soul Drain and Will to Fight.### **Patience**

#### **Ability: At the end of every even turn, if you have no Change of Winds in your hand and have 6 or less cards in your hand, add Change of Winds to the top of your deck.**

This deck is suggested for more senior players, although there are fast aggressive builds for newcomers too. Play a slow early game, ramping with Change of Winds and taunts. Put your hand back into your deck. Once you've done this, you can get extremely good cards for low costs. Build up a powerful attack, then cycle cards until they have no cost. Be careful not to mill yourself. Patience's spells are generally expensive, other than Change of Winds, but extremely strong.

Alternatavely, abuse Patience's overpowered spells to freeze your opponent's entire board, then boardwipe them with True Self. Unleash strong cards like MTT NEO and Placeholder Kris to kill enemies in one turn, after saving with Burgerpants.

This deck's Spells are Cold Winter, Defrosting, Exploration, Fridge,Snow Warning,Frozen Energy, Ice Prison, Ice Replica, Melt and Self Reflection.### **Bravery**

#### **Ability: At the start of every 3 turns, add a Recruitment your hand. If you have 4 or less cards in your hand, add 2 Recruitments to your hand instead. If your hand is full, add draft to your deck.**

This deck is one of the most newcomer-friendly ones. It focuses more on the attack of its monsters, aiming to deal massive amounts of damage in a few turns with the right setup, but it may be based on moving trough your deck fast and finding a specific and deadly combination of cards.
Having a deck centered around cheaper cards is also a good idea. This is known as 'Bravery Zoo', where cards are spammed quickly and continuously to overwhelm the opponent before they can place substantial cards. This quick drawing can be a disadvantage (preventable by using Reinforcement) against **decks** such as determination, perseverance or taunt spammers, since these decks can get rid of your cards easily, although if facing Bravery it's important to keep your guard up as it can remove the taunt from a card using 'Penetration'. If going for an aggressive approach it is advised to choose cheaper cards such as Temmie, Ice Cap and Snowdrake.

This deck's Spells are Acceleration, Ambush, Assault,Knights Shield,Froggit Trio, Overgrowth, Overheat, Penetration and Strength.

For the Previous Versions of Recruitment, see this page.### **Integrity**

#### **Ability: Turn end: If you spent more G this turn than last turn,earn 1G.**

This deck is not suggested for intermediate players. This soul type is great for playing high stat cards and getting a gold lead. A combination of medium cost cards with taunts and a few higher end cards is a decent option. Other cards which can give you extra monsters such as So Sorry are also good choices.
People using this deck may probably seek to use more costly cards mixed with taunts. The cost range suggested for Integrity users is 4-10. A use of Integrity that was popular a while ago, but now is significantly worse is to make a dog deck, essentially creating a deck comprised almost solely of dogs. The varied abilities of each dog, as well as their prices complimented each other well. Having multiple Dogamys and Dogaressas in the deck and putting them back into your hand to place them back onto the board again with cards like 'Break' or Doggo creates a good synergy by making use of their stat boost Magic.
Typically weak against aggressive decks, although some of the cards Integrity uses can tend to that. One of these cards is Spade King.

This deck's Spells are Cloning,Carousel,Wereform,Silly Strings, Expulsion,Fortune, Golden Hit, Inflation, Mecernary Hire,Investment and Shopping.### **Perseverance**

#### **Ability: Start of turn: give the enemy monster with the highest attack not under KR, KR.**

This deck is suggested for intermediate players and above. It is about poisoning damaged enemy monsters with karmic retribution (KR). Cards under KR give the killer +1/+1. The ways to remove KR without killing the card are to silence it, use Asriel or call it back to the deck/hand. A common practice for this deck is to use 'Pollutant Gas' when the enemy board is full or use 'Poison' and then use 'Worsening', 'Termination' or 'Contamination' on poisoned monsters. Any type of card can be used in this deck however cards such as Flowey, Asgore, Jumping Rabbit, or Skateboard Girl are good choices. Perseverance is a hard deck to create combos for, however it's mostly played with the intent of clearing the board or killing selecting monsters so a mild rush/zoo or control deck are viable options. Perseverance relies heavily on reactive damage, therefore cards that can deal damage quickly with Haste are suggested. Effective against board-reliant decks with no adequate counter. Lacks healing, as Siphoning is considered very weak.

This deck's Spells are Contamination, Poison, Pollutant Gas, Siphoning, Spider Web, Buttercup treat,Aftermath,Proceed,Worm Infuision,Petrification and Worsening.### **Kindness**

#### **Ability: Turn end: If its turn 3 or later, heal 1 HP to all allies. If no ally monsters are damaged, give the rightmost ally monster +1 HP.**

This deck is suggested for all types of players, and is usually the one most players start with. The soul type is about healing yourself and your monster. Kindness focuses more on healing, a possible tactic for kindness is to use 'Longevity' on a monster with taunt or to use one of the other healing cards for the same purpose. Typically those using this deck may want to opt for a longer 'wait it out' style of battle, this is done by having many taunts and medium to higher costing cards until you have enough gold to deploy them. Kindness is also very good at keeping a board lead, once the user got it. Cards like Migospel and alike can ensure survival of a monster that you want to attack with. A possible, but risky tactic is to create a OTK (one turn kill) deck by using many 'Force of Natures' before using 'Madjick' on a high HP card before switching the health and attack. Kindness is effective against slower board-reliant decks thanks to their Soothing. In general, the soul is about general stickiness and survival of their monsters - it can Heal allies after they attack, or boost their HP before that. Kindness can even avoid enemy monster's counterattack entirely by using Pie. That spell can also be combined with Papyrus, which is already a very good Legendary card.

This deck's Spells are Campfire, Feast, Force of Nature, Heal, Longevity, Octofriend, Pie, Soothing,Ultimate Heal and Test of Will.###  **Justice**

#### **Ability: Turn end: Deal 1 DMG to the lowest HP enemy monster.**

This deck is suggested for higher end intermediate players and above. All Spells of this class deal some form of damage. Because of this, it is important to note that Spells for Justice are often more expensive than those for other soul types. Dealing damage in the way these cards do is essentially the equivalent of having a charge card which ignores taunt. Because of this, it is more expensive than other damage dealing cards from other classes/soul types which have situational damage. These cards used to be cheaper until they were nerfed, but have since been re-adjusted multiple times, despite this they are still extremely effective and allow for some of the best combinations in game. Keeping a handful of 'Punishment' and 'Undyne's Spears' handy gives the player a great advantage when wanting to quickly dispatch an enemy monster or deal the finishing blow by bypassing taunt. Undyne is often used in this deck, it is especially good with Asgore and Mettaton NEO. Other cards which deal damage such as Vulkin, Moldessa, and Tsunderplane are highly useful. Justice typically uses a heavy board control playstyle with various select damage and split damage cards and can excel at most stages of a game if played correctly. Decently Effective against Bravery Zoo, and Determination, typically slightly weaker against Kindness and Integrity.

This deck's Spells are Blitz Quiz,Judgement, Explosion, Headshot, Multi Shot, Powerhouse, Punishment, Strafe and Undyne's Spears.
