Sealed Soul Conjurer

The first time a card is put into exile each turn,
you may pay {1}{u}. If you do, investigate.
{1}, Sacrifice a token: You may activate target
sealed card's abilities another player owns in exile
as if you were its owner this turn. If it would be
put into your hand, you may play that card from
exile instead and cast it without paying its mana
cost. Activate as a sorcery and only once per turn.
