New champ idea.

General passive would be "Don't give up" Which grants him the passive for when the champion dies they get to stay alive for a limited time/until dying by enemy again, but if get a kill or an asisst you continue to stay alive until limited time or get killed again. When you do die your life and enery bar would be back to full when your passive activates after dying.

The Q could be that you sent out two identical clones towards the enemy and they stay on the enemy champ until killed or limited time has pass. Any damage that your clones do to champions it restores life back to you 100% of the damage they do to the enemy champion or champions. Both clones can only attack one enemy champion at a time.

The W could be a shadow grab that is a point and click auto hit that can move through units and grab the champion with shadow grab snaring them if not killed while in snare they are then slowed.

The E could be make you go invisible for a limited time and can stay in it even if you get hit by anything but if you use w or ult or aa someone then you go out of it. However you are able to use your Q while invisible and you stay in invisible as you use Q but your clones are not invisible((Or they could be)).

Ult could be is when you ult one of your ally champions and they get your general passive. So If i were to ult Fiora she would be able to stay alive even after dead for a limited time or untill die again getting full health and mana back nothing decreased with stats and can use all of her abilites but can stay alive longer if get kills and or assists.
