Non vorrei sbagliarmi, ma mi sa che aveva ragione il tuo oppo.. goblin elfo umano etc. sono tutti SOTTOTIPI di creatura, così come rogue. I TIPI sono quelli che discriminano che tipo di carta stai giocando: stregoneria artefatto creatura etc. (ed eventualmente ci sono poi i supertipi come leggendario etc.)
Cita:
204. Type Line
204.1. The type line is printed directly below the illustration. It contains the card's card type(s). It also contains the card's subtype(s) and supertype(s), if applicable. [...cut...]
204.2. Card Types
204.2a The card types are artifact, creature, enchantment, instant, land, plane, planeswalker, sorcery, tribal, and vanguard.[...cut...]
Le CR fanno un esempio specifico poco dopo:
Cita:
204.3b Subtypes of each card type except plane are always single words and are listed after a long dash. Each word after the dash is a separate subtype; such objects may have multiple types. Subtypes of planes are also listed after a long dash, but may be multiple words. Each word after the dash is, collectively, a single subtype.
Example: "Basic Land -- Mountain" means the card is a land with the subtype Mountain. "Creature -- Goblin Wizard" means the card is a creature with the subtypes Goblin and Wizard. "Artifact -- Equipment" means the card is an artifact with the subtype Equipment.
204.3c If a card with multiple card types has one or more subtypes, each subtype is correlated to its appropriate card type.
Example: Dryad Arbor's type line says "Land Creature -- Forest Dryad." Forest is a land type, and Dryad is a creature type.
204.3d If an instruction requires choosing a subtype, you must choose one, and only one, existing subtype, and the subtype you choose must be for the appropriate card type. For example, you can't choose a land type if an instruction requires choosing a creature type.
Example: When choosing a creature type, "Merfolk" or "Wizard" is acceptable, but "Merfolk Wizard" is not. Words like "artifact," "opponent," "Swamp," or "truck" can't be chosen because they aren't creature types.
Il tuo oppo era quindi perfettamente legittimato a chiamare Rogue, perchè esso è un tipo di creatura (o meglio, un sottotipo del tipo creatura), esattamente come Faerie etc.
Sempre se non mi sbaglio, chiaramente.
EDIT: battutto di un soffio
