I can say that this piece deserves a score of TEN because of how harmless it is. It is also a new piece that is very much balanced and never seen before, complete with a new way to utilize an ability target, unthinkable by even Grand himself. Definitely a TEN.
There's a reason we don't have a flipped summoner in the game, this unit can easily turn 1 checkmate by teleporting using its knight teleports and then the ability target will be targeting the champion row of the enemy formation.
Also 4/10 balance.
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.
Teleporter is a solid 0/10 balance t1 mater.
