Despite the rather unassuming and unoriginal name these have worked quite well, so I have used the Magic Set Editor program to do up some better looking cards. So far there are twenty some different ones, the deck we used for today's game had two of each plus a dozen of the Attack cards for 66 total.
I want to add some more as we play, ending up with 46 unique cards and 14 Attack cards.
While the above cards have fairly old artwork, most of these have art cheerfully purloined from the net so I won't post them but if anyone wants the working file let me know.
