Glimpse the Spider-Verse

Look at the top three cards of your library.
Put one of them into you hand and the rest
on the bottom of you library in any order.
As long as you control a Spider, you may cast
Glimpse the Spider-Verse from you graveyard
by paying {u} rather than paying its mana cost.
If you cast Glimpse the Spider-Verse this way
exile it.
