Nomad Mythmaker
Creature — Human Nomad Cleric
, 
: Put target Aura card from a graveyard onto the battlefield under your control attached to a creature you control.
On the wild steppes, history vanishes in the dust. Only the mythmakers remain to say what was, and is, and will be.

Nomad Mythmaker's ability can target an Aura card in any graveyard, not just yours.
(wotc • 2007-07-15)
You don't choose which creature the Aura will enter attached to until the ability resolves. You must choose a creature the Aura can legally enchant. (For example, you can't choose a creature with protection from black if the targeted Aura card is black.) If you don't control any creatures that the Aura can enchant, it remains in the graveyard.
