i like it, but i think you should clear up the card text a bit, and make it a permanent. to use this as a spell, Zanz would have to change most of the coding for the entire card usage portion of the game, and then there would probably be serious bugs with that. as for the text, you might make it say 'you can use this ability 3 times' instead of '3 charges'.
Wait, you've seen the source code? How? I'll fix any bug you ask me to fix, just let me have access too.
The attributes for permanents are hard-coded, but the attributes for creatures aren't? Sloppy coding much?
A shorter form for your text replacement would be "usable 3 times".
