Start by reproducing the failure when opening the deck editor, then trace the reported path from MageFrame.showDeckEditor through CardSelector.loadCards and filterCards. Inspect SubType.values/fromString, CardInfo.getSubTypes, and MockCard construction in the named Java files. Done means the reported GUI workflow no longer reaches the OutOfMemoryError.
