Kyde, the Unsilenceable

You may cast Kyde from any graveyard or from exile.
At the beginning of each end step, a player at random gains control of Kyde.
Kyde is not affected by the ending of games. (It stays in its current zone, will not be shuffled back into its owner's library, and all counters on it remain.)
The voice of freedom can't ever be silenced.
