Allura Vysoren, Arcane Guide

At the beginning of your end step, if you've cast a
noncreature spell this turn, reveal the top five cards
of your library. For each card type among
noncreature spells you've cast this turn, you may
put a card of that type from among the revealed
cards into your hand. Put the rest on the bottom
of your library in a random order.

Archmage Bane. It's in the damned name, Yussa,
you fool."
