Aethergear troublemaker

Revolt - At the end of each combat step, if a permanent you controlled left the battlefield this turn, you may tap Aethergear troublemaker to tap up to two lands target player controls: these lands produce no mana this turn, and do not untap during their controller's next untap phase.
When Aethergear troublemaker revolts, if it revolted at the end of the previous combat step, put a 5/5 Gearhulk artifact creature token into play under your control.
