Description
She also requires you to cast the cards rather than put an artifact card into play, which opens it up to being countered

Just make sure not to use one of your other flicker spells on it once you take control most will return the flickered creature to its owner when it reenters the battlefield

It's great card draw over time

You have to be pretty ruthless when it comes to picking characters for this party
