Oracle Text

Whenever Tolarian Entrancer becomes blocked by a creature, gain control of that creature at end of combat.

Card Rulings

4/1/2008 The control change has no duration; you’ll retain control of that creature until the game ends or until some other effect causes it to change control. It doesn’t matter if Tolarian Entrancer leaves the battlefield, or if Tolarian Entrancer has already left the battlefield by the time the “at end of combat” ability triggers.
