Ok, I'll see what I can do.

You've got it

It is possible to get them from my database but not with the
webinterface.

The 2 most important tables in my database are 'oracle' and 'cards'.
'oracle' basicly contains the information from The Card Reference Oracle.
And 'cards' contains information on which card is in which expansion
with which rarity, flavor text and artist etc.
If possible only the table 'oracle' is queried but when information
from 'cards' is necessary 'oracle' is joined with 'cards'. In 'cards'
the is a separate tuple for each version of a card. So when you search
for expansion = 17 you actualy get another card than when you search
for expasnion = 18.
To get all cards which are in both 17 and 18 you would have to join
'cards' with itself. Approximately like this:
select * from cards c1, cards c2 where c1.expansion = 17 and
c2.expansion = 18 and c1.oralce_id = c2.oracle_id;
But since the interface doesn't allow you to perform joins you cannot
get this from my website. I don't know how much you know of mysql but
I hope this explains some details to you.
