Thanks to TheDark for the bug report on Urza's lands.
Note that the lands still don't work entirely correct, they give you the option to tap them for one mana even when they shouldn't anymore. This can be fixed when aslongas(cards) <1 is working.
Limitations:
- Operators for "greater than", "less than", "unequal" have not been implemented, but if a card actually needs them, you can use a preceding minus sign to negate a comparison. Example: -power=3 means "power not equal to 3", -toughness<=3 means "toughness>3".
- You can't use spaces when specifying such restrictions. Write "power<=3" instead of "power <= 3"
- You now need to use a space before the "<" and ">" commands that count the matches for lord(), foreach(), all() and aslongas(). So far we always did use spaces in front of them without actually needing to, now we need to.
- manacost restrictions don't take "X" costs into account. Example: Mistmeadow Skulkin (FUT) has protection from manacost>=3. Blaze has a converted manacost of 1, but when you cast it with an X of 2, then it actually has a converted manacost of 3 while on the stack, and Mistmeadow Skulkin would be protected from it, but currently it isn't.
Please review the code, I'll add a few remarks/questions of my own.
- 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
