Dhravian Indoctrinator

When Dhravian Indoctrinator enters the battlefield, exile target creature or planeswalker
an opponent controls until Dhravian
Indoctrinator leaves the battlefield.
At the beginning of your upkeep, put an indoctrination counter on the exiled permanent.
Then, if it has two or more indoctrination
counters on it, you may put it onto the
battlefield under your control.
