Rule: The player sends a reward or purchase to an ally's deck. <a id=\"variant-cooperation-01\"></a>\n- Ally deck service. Rule: One participant removes, restores or enhances the cards of another according to an explicit rule. <a id=\"variant-cooperation-02\"></a>\n- Hand transfer. Rule: Participants pass available cards to collect the desired combination from a suitable player. <a id=\"variant-cooperation-03\"></a>\n- Ally support. Rule: An effect provides another player with energy, additional cards, actions, or another resource for their deck. <a id=\"variant-cooperation-04\"></a>\n- Cross-player combo. Rule: Cards of different participants check common tags, statuses, order of actions or jointly prepared conditions. <a id=\"variant-cooperation-05\"></a>\n- Role incentives. Rule: Rules reward specialization of participants or require different deck functions to solve a common problem. <a id=\"variant-cooperation-06\"></a>\n- Variable turn order.
