Rule: A new copy of the selected card is added to the deck, sometimes preserving its improvements. <a id=\"variant-generation-01\"></a>\n- Temporary copy. Rule: The copy exists only for the current turn or battle and does not change the permanent deck after its completion. <a id=\"variant-generation-02\"></a>\n- Copy effect. Rule: A card repeats the properties of another card without creating a new permanent instance. <a id=\"variant-generation-03\"></a>\n- Replay / retrigger. Rule: The same card is reused, usually without repeating the regular payment or under a special rule. <a id=\"variant-generation-04\"></a>\n- Token generation. Rule: The effect adds a predetermined card to your hand, discard pile, deck, or other zone. <a id=\"variant-generation-05\"></a>\n- Random generation. Rule: The effect spawns a random card from a limited or common pool. <a id=\"variant-generation-06\"></a>\n- Discover pattern. Rule: The player selects a temporary or permanent card from several generated options. <a id=\"variant-generation-07\"></a>\n- Temporary transform. Rule: During the battle, the card changes shape and then restores its original version. <a id=\"variant-generation-08\"></a>\n- Self-replication. Rule: A card creates additional copies of itself when played or another condition is met. <a id=\"variant-generation-09\"></a>"},{"id":"context","title":"Context and limits","body":"Design taxonomy of basic rules and options, including card operations and external systems.
