Soul of Determination

Bestow {6}{w/b}{g/w}{b/g}
When Soul of Determination dies, return it to the battlefield under the control of the opponent that destroyed it. They may pay {8} to bestow it to a creature they control.
When enchanted creature leaves the battlefield, if it wasn't sacrificed or returned to your hand, return it to the battlefield.
At the beginning of your upkeep, add a +1/+1 counter to Soul of Determination or enchanted creature.
