Item active: throws a linear skillshot (similar to Leblanc's E); if it connects with an enemy champion, both the user and the target are Grounded (like Cassiopeia's W, it prevents dashes, jumps, etc) until the chain is broken. To break the chain, simply walk away (or die).
On a serious note, it sounds fun.
On a silly note, if they add tricksters glass back you could think you were chaining yourself to Ezreal and end up with Darius or Cho !_!
The chain should have a max duration obviously. But besides that it sounds like a fun idea.
Ok and I am a bit afraid it could be a bit too strong on juggernauts...
