Champion: Satelle, The Minion King
I thought Satelle, The Minion King would be interesting. His Passive would buff minions in one way or another: giving them increased damage or health or both. His attacks would be melee, also. Satelle could spawn all minions: Q would spawn a melee minion, W would spawn a caster minion, E would spawn a Siege minion (with extra mana cost), R would spawn a super minion. To Satelle's advantage, these minions would not give gold to the opposing team, but would still have the same health, damage, etc. as other minions. Also, these minions would not appear different to the opposing team, and they would appear green, like a puppet. He would make a great Bottom Support or Top Laner because of his tanky kit, and the Banner of Command would be buffed, since this item is rarely used. Either way, this item would be essential to his build. This would give the Bot Lane a strong Early game, and it would allow lanes to push tremendously. A unique feature for this Champion would be that he would change color depending on the team, and his release skin would be "Winion King" based on the popular saying.
Here is a picture of an old minion that I think would work great for Satelle
