If an Iczer has multiple copies of a Unit card in his or her Card File, a closed Unit can be Revived by spending 1 SP and pulling out another copy of that card. You can only have three copies of each card in your Card File, so you can only Revive each Unit two times. This is why most Card Files have multiples of each card.
Choose “Attack” to engage an enemy Unit in combat. The value of your Unit’s “AT” statistic is the damage your Unit can cause.
When you hit, the damage you do will pop up. When the enemy Unit is out of HP, it will be flipped over. Face down cards are called “Closed.”
Most Units choose their targets randomly, although some can target. You can only hit enemies within range. With RNG 1, you can only hit if there are no occupied rows between you and your enemy. With RNG 2, you can attack “over the head” of one unit, friend or foe. With RNG 3, you can attack “over the head” of two units, and so on.
After the fighting is over for the turn, little TOMBSTONE SYMBOLS will appear above your Closed Units. Click on the Closed Unit and the Tombstone will drop back, while the angel will come forward. Also, you'll see the translucent image of the card image. You can do this to as many cards as you want, as long as you have the SP. Then click "OK" to Revive them.
This Unit is marked for Revival. It’ll be Revived at the start of next turn.
