Rule: The opponent adds weak, harmful or unusable cards, reducing the frequency of useful ones. <a id=\"variant-interaction-01\"></a>\n- Forced discard. Rule: The opponent reduces the player's hand or forces him to choose which cards to lose until the next cycle. <a id=\"variant-interaction-02\"></a>\n- Mill. Rule: The opponent sends the top cards to the discard pile or other zone; the consequences depend on the reuse and the conditions of the lesion. <a id=\"variant-interaction-03\"></a>\n- Steal / control. Rule: The opponent takes a card, plays its effect, or temporarily gains control of it. <a id=\"variant-interaction-04\"></a>\n- Deck disruption. Rule: The opponent rearranges the cards, places a harmful card on top, or causes an unwanted shuffle. <a id=\"variant-interaction-05\"></a>\n- Card corruption. Rule: The effect worsens characteristics, changes the purpose, or replaces a useful card with another copy. <a id=\"variant-interaction-06\"></a>\n- Hand reveal. Rule: Rules allow you to view, reveal or remember your opponent's cards for later selection of actions. <a id=\"variant-interaction-07\"></a>\n- Type lock. Rule: The opponent temporarily prohibits drawing, searching, playing certain cards, or other operations with the deck. <a id=\"variant-interaction-08\"></a>\n- Build counters. Rule: The enemy ability punishes a specific type of deck, such as multiple plays or being dependent on one status. <a id=\"variant-interaction-09\"></a>\n- Disruption defense. Rule: Cards prevent attacks on the hand and deck, clear harmful cards, or soften restrictions. <a id=\"variant-interaction-10\"></a>"},{"id":"context","title":"Context and limits","body":"Design taxonomy of basic rules and options, including card operations and external systems.
