If you had to design a champion centered entirely on luck what would that champion have for skills?
Extra points if you can make them more balanced then the summoner before you.
tldr make a luck based champ balanced and you win life.
If riot was to ever introduced like non-consistent damage output. they would have to introduce a variable to make it more consistent.
Example... If champions Q based on you luck at maxed 5 points into it.. had the chance to do Anywhere on or between 50 - 500 Damage (Depending on how lucky you are you could hit poorly or very high)
There would need to be a new variable set of item called "Balance" Now now.. I know this sounds funny but in another game I play, Me as an archer I see my arrows hitting some funky damage. One arrow could do 100 damage while my other arrow does 200. (I shoot two at a time)
This "Balance" Modifier.. helps my damage output and the more I have the more consistent damage I do so now both of my arrows do around 175 each.
Balance works in funny ways.. with a luck based champion being able to do very high or very low damage and you could buy a balance item.. for more balanced damage that is not too weak or too strong.. Because of this you might question you need for this balance but would you be willing to gamble your damage for those higher hits?
Edit: This is I think would be a very interesting concept for a champion but they would need unique items to them therefore will probably never even have a though for riot. xD
Having to think about how much Balance you yourself want for your champion to do the damage output you wish to do.. Too much balance and you wont be "OP" or "UP"
I feel like it's worth mentioning that, to some extent, 
can have this, talking from experience. Like, sometimes I ult with the intention of killing one target only to get two others I didn't even know were low, too, and not on the minimap. This is often their jungler who I suppose wants one final camp before they recall, even if they're super-low on health. Alternately, I won't actually get the person for whom I was aiming because they hit Barrier or something, and instead kill an entirely unintended target(s).
Auto attack based champion that does 50% normal damage and crits for 400%. (crit chance is half as effective on them)
the ability to rightclick and build IE is all that´s needed...
Q. Sends out skillshots in 3 directions. The skillshots have a chance to be either red or green, if they are red they damage anyone it touches, if they're green it heals anyone it touches
W. Shield that has 3 random outcomes: Flat shield, shield of reverse damage reflection(you take damage when they attack), or spell shield, on the target
E. Teleport to the target point (like Ez E) but have a chance to stun yourself for 2 seconds upon teleport.
R. Global ult has a chance to give everyone on your team exp and damage everyone on your team, or freeze everyone on the opposite team for 4 seconds. (Lowish CD)
Q: Targeted ability that deals random damage between 75:200/100:225/125:250/150:275/175:300 and stuns for anywhere between 1:2/1:3/1:4/2:4/3:4
W: Targeted ability that pulls the target and you anywhere inbetween the two of you also shreds 10/20/30/40/50 armor. 550/600/650/700/750 cast range
E: 15% chance to get a crit for 125/175/225/275/325% damage, also the crit has 50% lifesteal
R: Summons 1/2/3 phantasms, phantasm's deal 100% damage and can crit, but take 200% damage, has a 50% chance of summoning another phantasm, also phantasms jump with you on w.
