This crafty loop sets up an endless cycle of sacrifice and resurrection powered by the relentless triggers of Blasting Station. When Leonin Relic-Warder enters the battlefield, it exiles Rescue Skiff, which conveniently sets up the Spacecraft's entry trigger to fish Leonin Relic-Warder right back out of your graveyard whenever it hits the bin. Meanwhile, Blasting Station untaps itself every time a creature enters or dies, letting you continuously sacrifice Leonin Relic-Warder to pelt opponents with endless damage.
