The modifier is outside of the "a X or a Y" clause. If the modifier were between either of the "a X" or "a Y" clauses, then you would be correct. Quote: ChrisF, Topic: Conjunction & Parsing

I think this needs further consideration, the card text is; "a B" or "an A". "an A" possibly being equivalent to "a Y"?
If this is not so, I believe the Wiki needs editing to include situations outside "a [modifier] X or Y", "a [modifier] X and Y", "a [modifier] X or a Y" or "a [modifier] X and a Y". Specifically, where X and/or Y are not singular, or where X and/or Y do not start with a consonant.
