Whenever an enchanted creature attacks one of your opponents, it gets +2/+0 and gains trample until end of turn.
Whenever an Aura you control is put into your graveyard from the battlefield, exile it. Until the end of your next turn, you may cast that card.
In some unusual cases, the Aura put into your graveyard isn't an Aura card. This may happen due to copy effects, for example. In these cases, you'll still exile the card and you may cast it.

You must still pay all costs and follow all timing rules when casting the card from exile.
