Gilligan

You may look at cards stashed under Gilligan.
When Gilligan attacks, stash a card from the top
of your library under Gilligan. When Gilligan dies, reveal all cards stashed under Gilligan. You may
cast any number of instant or sorcery spells from
among them without paying their mana cost.
Shuffle the rest into your library.
Shuffle a card stashed under Gilligan into your

until end of turn.
