Electromagnetic Champion would be cool

So I was just kinda thinking about different elements that Riot may have not thought of using, and I considered a champion with a sort of electromagnetic abilities. Maybe have a built in as a passive. Anyways, my idea why basically to take Rocket Grab and Death Sentence (or Resonating Strike) and combine them. So this electromagnetic champion's ability would be that he/she/it would have two magnets (obviously for the opposite poles). You would choose between them the same way you would choose Pick A Card. Attach one to either enemy or ally and it pulls that champion towards you (Rocket Grab) or attache the opposite to pull yourself towards them (Death Sentence). So similar to Broken Wings, it would be triple cast. Making an ability like that do damage would be kind broken I think, but hey I don't make the game and this is just a thought bubble. However I feel like a champion like this would be easily flexed if the abilities are right, and I'm sure Riot will have plenty of ideas for abilities.
