New Ability Idea

So i was playing Poppy last night and i got to thinking about how i love her Passive, the idea of giving a champion a long ranged attack on their passive is really cool. It feels like her passive could be better though, don't get me wrong it's not like she actually needs a change this was just an idea i had.

So the idea i had was, what if another champion or poppy had an ability like this.

Passive: Iron Ambassador

Innate: Poppy periodically gains the ability to throw her buckler. By holding the left mouse button down while this ability is up, poppy will start to slow by 30% over a 3 second channel. After 3 seconds she will throw her Buckler in a target direction dealing damage to all enemies it passes through until it hits a champion, her buckler's damage is reduced by 10% for each unit it passes through up to 50% reduced damage.

If poppy does not hit an enemy champion it will land on the ground at maximum distance, if it does hit a champion it will bounce off of them and return to poppy. When poppy regains her buckler she gains a small shield.

I thought it sounded cool to have a champion who had a skill shot on their passive that can be charged up, maybe if we got an ADC in the future who had a sling shot their passive would be similar to this. Without the bouncing effect and shield of course.
