Mod API Reference:CardInstance
CardInstance: An actual instance of a card belonging to a player or team. For example, when a player completes their 4th piece of a 4-piece reinforcement card, an instance of CardInstance is created, assigned a random ID, and given to the player/team.
This is an abstract type. For Reinforcement cards, you should use the ReinforcementCardInstamce, and for all other cards use the NoParameterCardInstance.
