New Champion Ability

Well I was watching a video by Jeremy "Gaming Curios" and he spoke about champion abilities and some that may be coming to league of legends soon, while watching I got really into the topic and came up with a ability, the ability is an ultimate/R move that allows the champion with this ability to make two portals by clicking on a wall or on the floor while pressing the R bottom, the champion with this ability will be able to pass through this portal also teammates can fire projectiles into one end and attack champions on the other end, this move also has one more function the portal can suck near by enemy champions into one end of the portal and push them out the other end by pressing the R bottom a second time, this ability will last for 20 seconds and can be disabled if the champion using this ability is killed or moved out of the range, I came up with this ability thinking of champion's ultimate abilities that miss or are dodged so this gives those champions another chance, one more thing this more has another ability if the portals are facing each other an attack will continuously pass through the portal gaining scailing attack damage and momentum every time it passes through just image what will happen if someone ran into a lux attack that's been in that loop a few dozen times can anyone hear instant death overall this is a ultimate for a support champion or mage that has a powerful range attack.
