Blue Mana Glimmer

Discard Blue Mana Glimmer from your hand:
Add {u}. Then, exile it from your graveyard.
Activate this ability only as a sorcery.
If Blue Mana Glimmer is in exile, you may pay
{u}{u}{p/u}{c} to cast it. When you do, create a
token that's a copy of it, except it's a land and an
island in addition to its other types and it isn't a
sorcery. Then, shuffle this card into your library.
