Avigio, Sun-Crown's Jewel

Lifelink
Whenever you gain life, you may search your
graveyard, hand and/or library for an Aura card
with converted mana cost less than or equal
to the amount of life you gained that could
enchant a creature and put it onto the battlefield attached to target creature. If you search your
library this way, shuffle it.
