Aeve is a legendary creature with storm, letting you make token copies of it for each spell that has been cast before it
Cards that generate tokens can also be a big benefit
Its a powerful finisher any of the top token commanders would gladly include in their decks
FYI: "Tournament-legal cards have a width x height measurement of 2.5x3.5, or 63.588.9mm. When it comes to the thickness, non-foil cards are about 0.012, or 0.305mm, thick. Foil cards, on their end, are a bit thicker as they have an extra layer on top of the card that creates that shiny, holographic look. When it comes to the corners of Magic cards, theyre rounded at a radius of about 0.125, or 3mm."
It does come with a stipulation, as You Are Already Dead can only destroy a creature that was dealt damage
