Active: Your next auto attack will turn a lane minion below 340 - 680 HP (based on level), granting you kill gold, healing it to full and transforming it into the same type of minion of your team's color. Enemies do not receive gold for killing the defector, and only one minion of each type can be turned per lane. Includes Super Minions. (90 second cooldown) [defected minions would have some sort of visual indicator, possibly a little banner on their backs] As with banner, you receive the gold from the minion's kills.
I think this would give some semblance of feeling of Banner of Command, but without the minion being overpowered.
