The Travelling Bard

The Travelling Bard enters the battlefield under target opponent's control.
At the beginning of each upkeep, the player that controls The Travelling Bard chooses an opponent. That player searches his or her library for a basic land card and puts it into their hand. Then that player shuffles his or her library. That player gains control of The Travelling Bard at the beginning of the next end step. If you lose control of The Travelling Bard, gain 2 life.
