Playable only during Main Phase, and only one per turn. Can attack/block, use its abilities.
One of the more critical attributes for characters are their power and toughness. These values are located at the bottom-right of the character card and are separated by a forward slash.
As you must use resources to play characters, their costs are also significantly important. There are two basic conditions that must be met in order to play a character, one being meeting the character’s node requirement and the other being paying the cost for that character. These two values are located in the top-right of the character card.
The "Node" value denotes the node requirement, or how many nodes you must have under your control, for the character card. The "Cost" value denotes the actual node cost that must be paid to play this character.
The next value is the character’s "Graze" value. If this character deals damage to an opponent, the opponent can choose to add that many cards from the top of their deck to their sleeping nodes pile. This value is located in the top-left of the character card and is labeled as "Graze".
You can use the spells of the characters that appear in Touhou. You may play as many as you want during your own Main Phase, but you cannot play them to interrupt.
"Equipment" and "Spell" are treated as part of the player they were set on. "Fantasy Being"-type cards come out in Sleep mode. "World Spell"-type can only be played once per turn, and come out immediately in Active mode.
If the card was played on the character whose name is under the Cost, you can ignore any Node and Cost requirements.
