Quote from the pet tutorial: "You can also command your pet by clicking the appropriate button in their sadfasdf below." Couldn't come up with a proper name for it? ;)
Okay, just a suggestion. Before implementing any improvement or new cards, will you please, please, pretty please with a cherry on the top fix the darn quickmatch problems?
@drgoldstring: It helps to read the instructions ;)
