General Kenobi

The first time General Kenobi defeats an
opposing creature, return it to the battlefield at
the start of the next end step.
"You were the Chosen One! It was said that you would destroy the Sith, not join them!"
When General Kenobi leaves the battlefield, give another target creature Hexproof, Vigilance and
two +1/+1 counters.
"If you strike me down, I shall become more powerful
than you can possibly imagine."
