Pokemon TCG is a really bad game to make an example out of in that case, since there's almost no correlation between types and playstyles/abilities.Every TCG has archetype-specific cards. It's so that certain types are better at certain things and to prevent every deck from looking basically the same.
Scarf is not a card that creates an archetype, it's a card that supports one. There's a couple of cards (mostly Grass) that work off the amount of Special Conditions an opposing Pokemon has. It would not make them playable, but it would give them an interesting option.
