The Gunky Runner (DA1-RB04) - Unknown Event

Ew-minance — When The Gunky Runner enters and at the beginning of the first upkeep in a game where it's your commander, shuffle three Gunk cards into each opponents library. (Gunk is a colorless sorcery card with no mana cost and cycling .)
Whenever an opponent loses life, they shuffle that many Gunk cards into their library.
Ready to run (You can have two commanders if both have ready to run.)
