So, this may sound stupid, but I can't find a link to the MtG plugin on this site. I am shamelessly asking for any help or direction, particularly if it's in plane sight an I'm just not seeing it.
In Lackey, go the Preferences and choose the Plugin tab (most left tab). In the Plugin Finder section, choose "magic" in the dropdown list and then click "Install or Update this Plugin". If it's not there, click "Find Plugins with Plugin Finder" to update that dropdown list. It should show you messages in the status log at the bottom and will tell you if there's any problems or what to do after it finishes downloading.
Thanks. Didn't even notice that.
