Clockroach is a unit card.
How to Get Edit
Alternate Art Edit
An alternate-art version of Clockroach was released in the Echoes of Eternity theme deck bundle . It cannot be crafted or destroyed for Shiftstone. The 1,100-gem bundle included a 4-copy playset along with the 5 Echoes of Eternity theme decks.
Clockroach's Summon ability affects all cards with the Clockroach unit type, not just other copies of itself. The ability does not affect Clockroaches zones other than the hand and deck; Clockroaches in the void, market, or in play will not be buffed.
