1. Milkman Singed- So this is a fairly straight forward idea. Not the most intense looking skin, but I still think it is a decent idea. Just toss a bottle on his back and dress him up so he looks like a milk man.
2. Money Bags Ziggs- So this is again a straight forward idea. Make his mine field a vault or something along those lines, and have his bombs be bags of money.
3. Yister Bunny (For Easter)- Now this is a long shot, idea came from a joke I made off his name awhile back. But anyways, Battle Bunny Riven....this can totally work. So put Yi in a bunny suit with a massive carrot and have his ult... make him bound away like a rabbit.
These are just a few of my ideas. May have more in the future, just thought I should put my ideas out there.
