Prison Tower

{t}: Add {c}.
{4}, {t}: Tap target creature.
As terrifiying to the people of Terran as anything
could be, and dubbed 'Prison Tower,' the mysterious
tower in the mountains lured people in and never sent
them back. Terrans wrote folk tales about it, spoken in hushed tones and to children at bedtime. What they
didn't know was that it was merely a gateway to
something unimaginable.
