This plugin contains a custom enchantment effect which allows you to mine a spawner and obtain it as a MobSpanwerEgg.
Just install TE-MobSpawnerEggEnchant.jar in TokenEnchant/enchants folder. Then you can either "restart the server" or "reload the plugin (not /te reload)". MobSpawnerEggEnchantment will automatically be loaded into TokenEnchant framework.
You need to add a new entry for "MobSpawnerEgg" under "Potions:" section in your config.yml.
