LaValle

The Taros Hoop:
When LaValle enters the battlefield he may
choose up to 4 creatures an opponent controls
and then exile them for 3 turns after 3 turns
the opponent may roll a D20
1-9 Creatures remain exiled for 3 more turns
then roll D20 again
10-19 Creatures return from exile but are tapped
20 Creatures return from exile with haste
