Battle Meditation

When Battle Meditation enters the battlefield, choose a creature you control. Tap that creature. You may choose not to untap that creature on your untap steps.
As long as the chosen creature is tapped, creatures you control have +1/+1. Whenever the chosen creature becomes untapped, Scry 1.
{3}: Exile Battle Meditation. Return it to the battlefield at the beginning of your next upkeep.
