Which values are considered copiable for a card?

In Magic: The Gathering, copying a card involves replicating various attributes of that card. The correct answer reflects that power, toughness, loyalty, mana cost, card type, rules text, supertype, subtype, and even expansion symbols can all be copied under certain circumstances.

Power, toughness, and loyalty are relevant attributes for creatures and planeswalkers which define their performance on the battlefield. Additionally, mana cost, card type, and rules text are fundamental characteristics that dictate how a card can be played and function within the game.

Supertype and subtype are also crucial in determining interactions and abilities within the game. The expansion symbol might not have direct functionality in gameplay like the others, but it serves as an identifier for that specific card set.

When a card is being copied, all these aspects can potentially change based on the nature of how the copy is created. Therefore, since all the mentioned attributes can be included in the combination of what gets copied, the conclusion is that all of the options listed fall under the definition of copiable values in the game.
