The Realm

The Realm is a new gamezone that can only be entered by spells or abilities you control.

The Realm can't be a target of your opponent.
Creatures don't loose counter or entchantments when they leave or enter this zone.
Permanents in The Realm can't be affected by spells or abilities that are not otherworldly.
Creatures that leave The Realm and enter the battlefield don't have summoning sickness.
You may activate spells or abilites to put creatures from The Realm to the battlefield as instants.
