Pharaqan's Disciple

Ordain (When you cast this spell you may tap a
creature you control that shares a color with it. If
you do, this spell becomes ordained.)
Whenever a creature enters the battlefield under
your control, if it was ordained, draw a card.
At the beginning of your end step, untap each
creature you control that didn't attack this turn.
To study life is to contemplate the Divine.
