Upload a virus to your opponent's clock. At the end of each of their next 5 turns it drains 8 seconds from their time. The clock floor still stops it from flagging them instantly.
You draft Computer Virus in Buff mode. Passive: it works on its own the whole time you hold it, with nothing to activate.
As a tempo card, it buys time: an extra move, a skip, or a freeze.
