What if we had an ability like Mr. Game and Watch's bucket?
If you've played Smash Bros you know what I'm talking about, but if not I'll explain. If Mr. Game and Watch uses his bucket at the correct time, he can absorb enemy projectiles. After he absorbs a certain amount of them (I think it's like 4 or something like that) the bucket is full. At this time, he can toss the contents of the bucket back at the enemy whenever he chooses! Now, I'm not saying we should have a champion with a giant bucket, but I think it would be cool if you could absorb enemy projectiles (or your allies projectiles) and toss them back at them!

. Then again,
has the same problem with his wind wall.
