Command Cards
Every unit has between one and three Command Cards attached to it. When taking a unit into battle you are also taking the attached Command Cards into battle. You need these cards to perform any action during a battle - whatever you want to do, you will need the right Command Card to do it.
Using Command Cards costs Command Points. These are also your Hit Points. If i use them all up, you lose. Some Command Cards require a specific amount of Elite Stars. These Elite Stars can be obtained by playing Command Cards like Orders From HQ, or by Elite Units (units with the 'Elite' ability) on the battlefield.
One from two cards are automatically granted to the player at the start of each battle. They only exist inside the battle and their differing strength constitutes a compensation for the second player.
Those cards are First Move and Second Move.
After using Command card, cost of this card increase by +1 every time you use it. So i is good to have a large number of different Command cards.
Basic Command cards - Order, Operation, Oreder from HQ, Fireteam, Special Force, Resuply, mostly offer elementary maneuvers which every army needs. You can use them to move units, initiate attacks or resupply your Command Points. Accordingly, these cards are the easiest to find. They can be attached to every unit you get from a booster pack .
Advanced Command Cards are generally more powerful than basic cards. They can be used to call in limited air support or give bonuses to your units. However, many Advanced Command Cards only affect a single unit type (i.e. guns, infantry or armored vehicles) and are only useful for certain strategies. These cards can be found in the Enhanced Booster, the Premium Booster and the Mystery Box
Evolved Command Cards are the most powerful cards in the game. They let you call in devastating air strikes or order offensive maneuvers like flank attacks and pincer moves. These cards are valuable additions to every army. Evolved Command Cards can only be created through Composing or found in the Mystery Box. You can recognize them by their golden background.
Composing
Composing lets you add a unit’s Command Card to another unit. You can only compose units of the same Rarity and faction. Additionally, the second unit must have only one Command Card attached.
Composing destroys the second unit and adds its Command Card to the first. If the first unit already has three cards attached, a new Command Card will be created. This new card will always be a random Evolved Command Card.
To make Composing Rare and Mythic Rare units easier we have introduced the Field Kitchen. This unit is not meant to be used on the battlefield but allows you to keep your valuable combat units when Composing. It is available through the Mystery Box. At quality level 4 you will always get one Rare field kitchen, at level 5 you will always get a Mythic Rare field kitchen with an random Command Card attached.
Units you buy in the Marketplace can have every type of Command Card attached. However, units with evolved Command Cards will most likely cost a lot more Coins than those with basic cards.
