Aethergear insurgent

Revolt - At the beginning of your end step, if a permanent you controlled left the battlefield this turn, you may search in your Library for an Artifact card, reveal it, put it in your hand and
pay for its mana cost minus {1} or bury it.
When Aethergear insurgent blocks an Artifact creature, if Aethergear insurgent Revolted last turn, destroy that creature.
