Your opponent skips their next three turns, but the prison is fragile: if you capture anything while it holds, it shatters and their remaining skipped turns are refunded.
You draft Time Prison 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.
Affects your opponent's whole army.
