Who has the advantage here?

  Who has the advantage here?  White is playing a standard set of chess pieces.  Black has 3 of the following pieces that replace his queen and both of his rooks.  The pieces work in this way.

  They can start out as either a Rook, Bishop, or Knight. Each can individually start out as whichever black wishes.  They can "polymorph" into any of the three.

However, it taks a turn to do so with no move.  In other words, black can spend his turn to transform all three (however many are left on the board) into any of the three original choices.  Transforming a piece can announce check.

  There is one exception to all of this.  The black player is allowed one "kamikazee" move in the game.  One of the three pieces can attack any piece (even his own) in any of the rook/knight/bishop fashions, except sacrifices itself in the process.  White does not have to spend a turn to capture the piece that took his piece, he simply moves next.  Another restriction is that this "suicide move" ends all polymorping and threat of polymorphing for the entire game for the other two pieces. 

However, before the suicide move is performed the king can not move into a potential suicide move threat nor can white move another of his pieces wich would expose his king to a suicide move from a piece eligible to perform such an attack.
