Players cannot cast spells that contain "all" or "target" in their
text, or which are printed at any rarity other than common. You can
cast spells with the word "protection" in their text without paying
their costs. If Safe Space is in your graveyard or is in exile, you
cannot cast creature spells.
Detain a creature you control: Target spell or permanent loses its text. Any player may activate this ability.
