Main deck Magics can animate an Aura via Enchantress's ability, so you can use the resulting Aura-Minion during resolution of the spell.

The Magics in the Maybeboard cannot be used to perform this interaction, though they are commonly mistaken to work this way. They DO work though if you have an already-animated Aura-Minion, just like various Artifacts can be cast "into the hands" of a minion.

Examples:

You have a Wildfire out.

• You CAN cast Blink to animate it and then teleport it to a nearby location.
• You CAN cast Gift of the Wolf to animate it and then give it +2 power via Gift of the Wolf's effect.
• You CAN cast Shatter Strike to animate it and then have it target an enemy to strike with the spell's effect.
• You CAN cast Whirling Blades to animate it and then have it step 2 spaces, doing the Whirling Blades thing.
• You CANNOT cast Duel to animate it and then have it fight an enemy; it must have been animated by something else earlier in your turn to be able to target the enemy to even cast Duel to begin with.
