Baneful Bunker

The user is protected from most attacks made by other Pokemon during this turn, and Pokemon making contact with the user become poisoned. This move has a 1/X chance of being successful, where X starts at 1 and triples each time this move is successfully used. X resets to 1 if this move fails, if the users last move used is not Baneful Bunker, or if it was one of those moves and the users protection was broken. Fails if the user moves last this turn.
