...when you donate money to the game on it's birthday and on Christmas as a gift to Zanzario.
...when you buy 12 copies of the latest cards and upgrade half of them when a new version comes out, just because you have the electrum to do it.
...when you capture a spider in your backyard and bring it indoors to help you battle an Air deck as your pet.
...when you've done at least half of the things on this thread.
