There is one important thing about coding such cards in direct combination with "limit:x". You have to put "limit:x" always before "myUpkeepOnly", see Firemane Angel as an example.
An auto line with "...myUpkeepOnly limit:x" does not work! So, the only working combination is "...limit:x myUpkeepOnly".
- Adding most missing sets. _cards.dat only contain 1 card so that the file is not submitted empty, but other than that...hundreds of cards to add... feel free to copy/paste existing files from the forum if you trust their content
