Rule: A card is strengthened if there are other cards of the same group in the hand, deck or among those played. <a id=\"variant-synergy-01\"></a>\n- Threshold synergy. Rule: The effect turns on after reaching a specified number of cards, items, charges or draws. <a id=\"variant-synergy-02\"></a>\n- Duplicate synergy. Rule: Several instances of the same name or characteristic reinforce each other. <a id=\"variant-synergy-03\"></a>\n- Singleton synergy. Rule: The effect requires no duplicates or encourages a variety of cards. <a id=\"variant-synergy-04\"></a>\n- Deck-size scaling. Rule: The power of a card or passive effect increases with a large, small, or other specified deck size. <a id=\"variant-synergy-05\"></a>\n- Composition synergy. Rule: The effect checks the proportion or absence of attacks, skills, resources, suits and other categories. <a id=\"variant-synergy-06\"></a>\n- Discard synergy. Rule: Voluntary or forced discard becomes a source of resources, damage, drawing or returning cards. <a id=\"variant-synergy-07\"></a>\n- Exhaust synergy. Rule: Temporarily removing cards activates other effects and helps reduce the working deck of the current battle. <a id=\"variant-synergy-08\"></a>\n- Trash synergy. Rule: Destroying cards provides additional benefit, turning deck clearing into a growth engine. <a id=\"variant-synergy-09\"></a>\n- Cycle synergy. Rule: Frequent collection, reuse and transition between cycles trigger associated rewards. <a id=\"variant-synergy-10\"></a>\n- Curse synergy. Rule: Curses, wounds and other unwanted cards are allowed to be turned into benefits or used as a bonus condition. <a id=\"variant-synergy-11\"></a>\n- Empty-zone synergy. Rule: The effect increases with an empty hand, deck, discard, or absence of a certain category of cards. <a id=\"variant-synergy-12\"></a>\n- Set / poker-hand synergy. Rule: You need to collect a sequence, set, suit, rank or other formal combination of cards. <a id=\"variant-synergy-13\"></a>"},{"id":"context","title":"Context and limits","body":"Design taxonomy of basic rules and options, including card operations and external systems.
