| Common Card | Recommendation |
|---|---|
 Maneuvering Fire | Rating: ★★★★★ - 0-cost AoE Attack - Can be used on turn 1 due to Initiation - Exhausts after use, compressing the deck |
| Quickdraw | Rating: ★★★★・ - 0-cost Single-Target Attack - Can be used on turn 1 due to Initiation - Exhausts after use, compressing the deck |
| Hidden Bullet | Rating: ★★★★・ - 0-cost Single-Target Attack - Can aim for high damage with retain - Doesn't return to the deck, so it won't get in the way |
| Rage | Rating: ★★★・・ - 2-cost Single-Target Attack - Becomes 0-cost if there are no other character's Cards in hand |
| Shock | Rating: ★★★・・ - 2-cost AoE Attack - Applies Vulnerable to increase damage taken |
| Atomic Decomposition | Rating: ★★★・・ - 2-cost AoE Attack - Ignores Shield with Piercing Damage |
Maneuvering Fire
Maneuvering Fire has Initiation, allowing you to always perform an AoE Attack on the first turn. It doesn't use AP and Exhausts, so you don't have to worry about it cluttering your deck. It's generally a card worth taking.
Quickdraw
Like Maneuvering Fire, Quickdraw is a 0-cost Attack Card with Initiation and Exhaust. Although it's a single-target Attack, you can expect additional damage from Mark.
Hidden Bullet
Hidden Bullet is a 0-cost Attack Card with retain. Since its damage increases each time it's retained, you can aim for massive damage at 0-cost in long battles.
Rage
Rage is a high-multiplier Single-Target Attack Card. It's heavy at 2-cost, but becomes 0-cost if you have no other Combatant's Cards in hand. It's extremely powerful if you have extra AP from characters like Mika and can use up all other Combatants' Cards.
Shock
Shock is a valuable AoE Attack Common Card. It can also apply Vulnerable, making it useful when you want to continue chipping away at HP. It's invaluable in boss battles where you want to defeat multiple minions at once.
Atomic Decomposition
Atomic Decomposition is also a Common Card that can perform an AoE Attack. Its appeal is its Piercing Damage that can ignore Shield. Use it or Shock depending on the Chaos.
Draw-Type Common Cards
Draw-Type Common Cards List
| Common Card | Recommendation |
|---|---|
| Gear Bag | Rating: ★★★★★ - 1-cost, draw 2 Cards - Effectively 0-cost due to Combo - Exhausts after use, compressing the deck |
| Attack! | Rating: ★★★★・ - 0-cost Search Card - Excellent synergy with characters like Haru |
| Quick Shelling | Rating: ★★★・・ - 0-cost, draw 1 Card - Can also Attack at the same time |
| Rally | Rating: ★★★・・ - 0-cost, draw 1 Card - Increases the Count of all enemies |
Gear Bag
Gear Bag is an exceptional Card that lets you draw 2 cards for 1-cost. In addition, it has Combo, making it effectively usable for 0-cost. It is recommended to pair it with characters who benefit greatly from drawing cards, such as Yuki and Nia.
Attack!
Attack! is a Card that lets you Search for 1 Attack Card from your deck and add it to your hand. It has extremely good synergy with characters who reuse powerful Attack Cards like Haru.
Quick Shelling
Quick Shelling is a 0-cost Card that allows you to Attack and draw simultaneously. It's easy to use in various situations and helps broaden your strategic options.
Rally
Rally is a Card that not only lets you draw but also increases the Count of all enemies. It's a card you'll want to actively include in Chaos runs with enemies that take extra actions after their turn.
Shield Common Cards
Shield Common Cards List
| Common Card | Recommendation |
|---|---|
| Energy Barrier | Rating: ★★★★★ - Gain Shield for 0-cost - Can also gain AP - Exhausts after use, compressing the deck |
| Relentless Endurance | Rating: ★★★★・ - 2-cost Shield gain - Can be used at any time with retain |
| Fortitude | Rating: ★★★・・ - Gain Shield for 2 consecutive turns - Good synergy with enemies that use consecutive Attack actions |
| Protective Shout | Rating: ★★★・・ - Gain Shield for 1-cost - The amount gained increases if you don't have a Shield |
Energy Barrier
Energy Barrier is an exceptional Card that gives you Shield and even restores AP for 0-cost. It also Exhausts after use to compress your deck, so you should prioritize acquiring it when you see it.
Relentless Endurance
Relentless Endurance is a Shield Card with retain. It provides a large amount of Shield and is costly, but its appeal is that it can be used at any time. Including it in your Vanguard's deck will increase stability.
Fortitude
Fortitude is a Card that lets you apply Shield for two turns in a row. It's somewhat unsuitable for enemies that alternate between attacks and special actions, but it has excellent synergy with opponents that Attack consecutively.
Protective Shout
Despite being 1-cost, Protective Shout allows you to gain a large amount of Shield when used while you have no Shield. It's a cost-effective Card that you'll want to prioritize, but be aware that it has poor synergy with equipment that grants Shield every turn.
Support Common Cards
Support Common Cards List
| Common Card | Recommendation |
|---|---|
| Strategic Starting Point | Rating: ★★★★★ - Gain 2 Ego Points - Exhausts after use, compressing the deck - Shines in Chaos |
| Tactical Reformation | Rating: ★★★★・ - Reduces the Cost of the next Ego Skill used by 1 - Exhausts after use, compressing the deck - Shines in Chaos |
| First Aid Kit | Rating: ★★★★・ - Effectively a 0-cost Heal thanks to Celestial - Exhausts after use, compressing the deck |
| Iron Wall | Rating: ★★★・・ - Gain buffs to Shield amount gained and damage taken reduction - Usable from the start of combat with Initiation |
| Camouflage | Rating: ★★★・・ - Creates a 1-turn window by granting Evade - Easy to recover with 2 draws next turn |
Strategic Starting Point
Strategic Starting Point is an exceptional Card that grants 2 Ego Points. Since it can be used in every battle in Chaos, including it allows you to use your Ego Skill frequently.
Tactical Reformation
Tactical Reformation is a Card that reduces the Cost of the next Ego Skill you use. Although inferior to Strategic Starting Point, this is also effectively the same as gaining 1 Ego Point, making it invaluable in Chaos.
First Aid Kit
First Aid Kit is a Heal Card with Celestial. By combining it with Khalipe or Haru, you can Heal without using AP.
Iron Wall
Iron Wall is a defensive buff Card that can be used with Initiation. It can buff your damage reduction and Shield gain at the start of battle, allowing you to raise your team's Durability by one level.
Camouflage
Camouflage is a powerful Card that can grant Evade. In CZN, many enemies alternate between attacks and special actions, so a great aspect of this card is that using just one can sometimes create a 2-turn window.
What Are Common Cards?
Cards that appear in Chaos regardless of your team composition
Common Cards are Cards that can be acquired in Chaos. Unlike Epiphany cards, any of these Cards can potentially appear, regardless of your team composition.
There are Class restrictions
Common Cards are assigned a Class, and only characters of the corresponding Class can acquire them. Be aware that depending on your team composition, there will be Cards that are impossible to obtain.
Acquiring too many is a disadvantage
Acquiring a Common Card increases your Faint Memory Point. If you acquire them without thinking, your Save Data will be corrupted due to exceeding the Faint Memory Point limit, so avoid acquiring unnecessary Cards.
How to Obtain Common Cards
Obtain in the Safe Area
Common Cards can be obtained by using Train in the Safe Area. By spending 50 Credits, you can acquire one of three randomly presented Cards.
Using Train makes Rest unavailable
You can only choose one of either Rest or Train in the Safe Area. If you want to recover HP or Stress, prioritize Rest.
Obtain at the Dellang Shop
If the Dellang Shop has appeared in the Safe Area, you can also acquire them by purchasing from the shop. There are no purchase limits; you can buy all the items in stock as long as you have enough Credits.
Obtain from Events in the Unidentified Area
Common Cards can sometimes be obtained in the Unidentified Area as well. If there's a specific Card you want, choose the Common Card option.
