Malina, Arcane Aspirant

As Malina enters the battlefield, choose a card
type and one of its subtypes.
If a cycling ability would cause you to draw a
card, you may instead search your library for a
card of the chosen subtype, reveal it, put it into
your hand, then shuffle.
Spells you cast of the chosen type cost {1} less to
cast for each card you've cycled this turn.
