yugioh star deck Complete Custom for Yu-Gi-Oh! 5D's YuGiOh Structure Deck Cyber Strike

For "actual" uses, it has seen a few comedic stints in various levels of play

While its expensive to cast, activating its monstrosity ability gives you a token copy of it

Since there are no life totals, damage is of no consequence to you, though it still gets rid of creatures

It's also treated as Dark Magician on the field, allowing you to use other Dark Magician support cards that require it on the field

You can even use Vivien as a makeshift Birthing Pod effect with cards such as Planebound Accomplice and Felidar Guardian, allowing you to easily assemble powerful combos

These are mentioned in the Extra Deck section later on
