For ten loyalty, you get an emblem that reads, Whenever an Artifact is put into your graveyard from the battlefield, return that card to the battlefield at the beginning of the next end step.

Presumably Kadabras return sparked the creation of this set, as this is the first time since Gen II that all the original Pokemon can appear together in card form
Why Enchantress Works in Cube When supported correctly, Enchantress offers a refreshing play-pattern: It rewards deckbuilding and drafting skill (choosing the right enchantments, sequencing)
