Questia, League Archivist

Partner with Shmaag, Izzet Corsair

The first time each turn you discard a non-land
card to pay a jump-start cost, you may exile that
card. You may cast that card for as long as it is
exiled and its cost is reduced by {1} for each time
Questia has been cast from the command zone.

{t}: Add {u} or {r}. Spend this mana only to cast instant or sorcery spells.
