For your opponent's next 3 turns, a poltergeist shoves one random enemy pawn one square sideways at the start of each (when a side square is empty).
You draft Poltergeist in Buff mode. Passive: it works on its own the whole time you hold it, with nothing to activate.
As a attack card, it removes or detonates a piece directly.
“The rattling is free. The giggling costs extra.”
