Boonweaver Giant
Creature — Giant Monk
When this creature enters, you may search your graveyard, hand, and/or library for an Aura card and put it onto the battlefield attached to this creature. If you search your library this way, shuffle.

The Aura card must be able to legally enchant Boonweaver Giant. For example, you can’t put an Aura with enchant land onto the battlefield this way.

If Boonweaver Giant isn’t on the battlefield when its ability resolves, you can’t put any Aura onto the battlefield. You may still search the appropriate zones and shuffle your library, if applicable.
