Good grammar deck

SomeCallMeChris basically said it all. The book is for understanding grammar explanations, not reading practice, and after a while, romaji becomes way more difficult to read anyway. Finally, if you use the deck I linked to revise, you're not going to be remembering the romaji somehow, there's no romaji in the deck. So ultimately, there's really no reason to worry. While I read this series cover to cover, it's designed for reference mostly, so it makes sense that it has romaji, because that makes it far more useful to people with a linguistic interest in Japanese, who might not have it as a language they actually understand.
