What are you talking about? What is this so-called "Summoner"? I never heard anything like that in the game. Also, you can't turn one checkmate using this piece. If you teleport using the horse teleport, the front ability target will disappear. And beside, this piece is too expensive to actually do anything worthwhile. The teleport from ability target is useless if done wrongly. It can only target one thing, and you can only use the backward ability target because the front ability target will disappear when you move too far front.
