Sai'Din, Jeskai Archmage

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
Noncreature spells you cast cost {u}, {r} or {w} less to cast. This effect reduces only the amount of
one colored mana you pay. (For example, if you cast a Instant, or Sorcery spell with mana cost {1}{u}{r}, it costs {1}{u} or {1}{r} to cast.)
{u}{r}{w}, {t}: Search your library for three noncreature, nonland cards, reveal them, and put them into your hand. Then shuffle your library.
