How it works
Play Strip Mine.
When Strip Mine enters, Retreat to Emeria triggers, creating a 1/1 Kor Ally creature token.
When the Kor Ally enters, Haru triggers, earthbending Strip Mine.
Activate Strip Mine's second ability by tapping and sacrificing it, targeting another land.
Haru triggers, returning Strip Mine from your graveyard to the battlefield untapped due to Spelunking.
