Labyrinth of Mirrors

Defender
Whenever Labyrinth of Mirrors blocks a creature, exile that creature. Roll a six-sided die, and place a number of time counters on it equal
to the result. At the beginning of its owner's upkeep, they remove a time counter. When its owner removes the last, return it to the battlefield under its owner's control.
Please do not leave a trail of breadcrumbs to mark your way. It attracts the rats; big ones.
