I have a character idea

The character is a leprechaun named Shamus and he is powers by gold instead of mama. His passive is greed: character gains ad based on gold. His Q is a move called Winds of the Isle and he gains speed and trample, and the trample power is varied upon amount of gold. His W I need to think about but it is called Luck of the Irish and it would be a shield of sorts and it is a rotating 4 leaf clover. His E is a taunt called A Little Jig, obviously it is a dance. Finally his ult is End of the Rainbow, he throws a pot of gold a short distance and it deals damage based on level and am out of gold and if it hits an enemy champion they get slowed, and the pot of gold has a range where the number of enemy champions inside it heightens both attack and speed based on how many are in the proximity of the pot of gold.

For all that have read this I say thank you and I welcome advice or ideas.
