Glimpse the Eternities

Ignite up to two target creatures. They gain "Remove three loyalty counters from this permanent: Exile another target permanent,
then return it to the battlefield tapped under its owner's control." (To ignite a permanent, put three loyalty counters on it. It becomes a planeswalker and loses all other types and abilities.)
Just a glimpse of the Blind Eternities will turn the most stoic of heroes mad. It can take a lifetime to recover from the madness.
