New champion

I've had an idea for a new champion for some time now I was thinking of a hero that can manipulate matter into gateways like portals. Like he can summon a portal in front of himself and behind an enemy then whatever skill shot passes through the portal on one side will come out the other, or something like that. Another ability could be an active that he uses to get resistance form another demention to protect himself for a while or maybe a "portal shield" that absorbs any damage and if there is another portal open somewhere and he is hit by a skill shot it will appear there instead of damaging him. The last ability could be where he opens up a portal to release a damaging force from another demetion. He can put down that location of the portal after that he can choose the direction of where the force will go before it opens. And his ultimate being a portal he can summon to take him anywhere on the map but only he can pass through it. I haven't really decided on a name yet, maybe something like Portal Gaidor or a weird alien name like Kuh'Rak or something. Please let me know what you think of this idea
