Trekking Soldier

Trekking Soldier is summoned with {e}{e}{e}.
At each upkeep step, remove an {e} from Trekking Soldier. If no more {e} remain, sacrifice Trekking Soldier and summon a 4/4 Black Serpent creature token. The Black Serpent token gains all the tokens on the Trekking Soldier before it's sacrifice.
With my lantern filled with oil and my blade sharp, my life will remain as mine.
