Strategy: Bishop Edit
Bishop pairs well with minions that do not block movement, such as Phantasm or Ghost. The line would look unbroken, but the bishop could set up a decisive attack if the other player does not realize it has freedom to move. In addition to this, you can set the Bishop up in key points to prepare a diagonal attack and set up some board control by abusing the power of its ability to traverse the diagonals in an unrestricted manner.
Bishops may be used in a variety of ways and remain useful throughout the game. Conventionally, during the early to mid game, bishops are either used to defend pieces which provide central control or pressure a weak portion of the opponent's army from a safe distance. If the opponent is not careful, well placed bishops can pressure expensive pieces and thus lead to underdevelopment. Upgraded bishops have lateral movement and (at +++) the ability to teleport, which provides vastly improved coverage and cross-board pressure.
While Bishop-(un-upgraded) is still considered a playable unit (as it trades relatively well), Bishop+ is considered to be a good deal better. The reason for this is the ability to move and essentially "switch colors", allowing a single Bishop+ to be able to get anywhere. The Bishop's effectiveness drops in the middle game.
The bishops are particularly good for the slingshot move, where the bishop and another stronger champion, like the queen, are on the same diagonal. However, this move can be easily blocked by an enemy minion moving onto the same diagonal (given that it has protection).
In the late game, bishops can control almost any important square of their color due to their high mobility in open boards. This will normally let one promote a piece or greatly reduce the range their opponent's piece can move. It may also pin or skewer a champion which is limited to cardinal directions, which could lead to a devastating trade.
At +++, Bishop's valkarie-like teleportation move allows it to be very mobile in its escape and hard to pin down.
Normal (non-upgraded) bishops, while having infinite diagonal movement and attack, can't change colors. A white bishop can only control white squares unless its position is changed by a swap position ability from another piece. If a player only has one normal bishop, they enemy could place their important pieces on the opposite color, avoiding potential threats.
Bishops are susceptible to pins and forks, especially in the early or mid game when other pieces hinder its movement. While an upgraded bishop can easily play around such tactics, the normal bishop will normally be traded away or ignored due to its loss of control.
