Seals based champion ideas..

I have some ideas about a champion who uses seals, basically like seals from naruto (those black circles with weird shaped letters).. I'm not actually sure how that champion should look like, but it can be like a mage who puts seals on you and then interacts with it and seals can prevent you from performing specific actions, or it can some kind of an assassin/ninja type champion that can put long lasting seals on walls, the ground or enemy champion and then teleport to it (like minato lol), I can Imagine an assassin that gets to you marks you and then leaves, and after some time comes out of nowhere and bursts you down it would be so fcking cool!!
