Covenant Hydromancer

Tribute 1 (As this creature enters the battlefield, an opponent of your choice may place one +1/+1 counter on it.)
When Covenant Hydromancer enters the battlefield, if tribute wasn't paid, return target creature an opponent controls to its owner's hand.
With many Vazdurek territories beset by a constant onslaught of floods and tidal waves, it is no wonder that so many of their sorcerers embrace the path of water magic.
