Aurora, Emissary of Lightning

If you play an attack action card then resolve Aurora’s activated ability to create an Embodiment of Lightning with the intent of the attack action card getting go again, that attack you played will not get go again from the Embodiment of Lightning. That is because the attack action card has already been played. You will need to resolve Aurora’s activated ability first and create the Embodiment of Lightning, then play the attack action card to have it get go again from the Embodiment of Lightning.
