The Negative Zone

When The Negative zone enters the battlefield,
each player chooses three nonland permanents
they control other than The Negative Zone and
exile them.
{2}: Put a Release counter on The Negative Zone.
Any player may activate this ability. If a player
were to put the twelfth counter on The Negative
Zone, they destroy it, and put each card exiled
with The Negative Zone onto the battlefield
under their control.
