Not all cards in saga are the same. Some single can make a full unit (Dragons would be one such example), others require multiple cards to make a full unit (human archers).
To check the specifics of a card, do the following:
- Push the ‘s’ key in game, or click on your Stronghold
- Click the Card Management icon
You can now browse through your cards. You’ll notice that some have a value labeled CP listed, with a number next to it. See below for an example. CP stands for command points. All units have a maximum CP value of 30. So if you are creating a unit of Elven Warriors, each card has a CP value of 2. All units have a base CP value of 5, so if you have 12 Elven Warrior cards in your unit at a CP value of 2 CP per warrior, your new unit will cost 29 CP to deploy during quests and PvP matches.
Some units require 12 cards total for a full unit (as the example above details), others require 25 cards, and some a single card.
Another example would be the coveted Great Dragon. This card has a CP value of 25. Add the 5 CP for the unit base, and a Great Dragon will cost 30 CP to deploy.
As a general rule, any card with a CP value higher than 6 will be a single unit. Eagle Riders, Treants, Charioteers etc all have a CP value of 6, so it would thus take 4 identical cards to make a full unit. If you are short of the cards needed for a full unit, you will still be able to create and use the unit for quests and matches while you attain more cards to complete the unit.
