Rig one of your pieces with charges: for the game, whenever it captures an enemy piece the squares around the capture are cleared of enemy pieces. Kings are never caught in the blast.
You draft Demolition Charge in Buff mode. Activated: you choose when to use it, and using it is your move for that turn.
As a attack card, it removes or detonates a piece directly.
“It goes off exactly where you point it.”
