The fact that you can play Vivi and immediately play any number of free spells to grow Vivi and deal damage to the opponent makes it a very scary card
Whereas normal version of RUG/Arabian Aggro can easily lose to the card, this version at least plays a mix of countermagic to handle critical threats like The Abyss, and after sideboard you can also bring in things like Tranquility, Whirling Dervish, and Concordant Crossroads (which acts as a one mana removal spell for The Abyss because they are both Enchant Worlds, and also makes all of your attackers hasty, shortening the clock)
BPhillipYork: I think is fun, really kind of sad it doesn't have white, because there's a lot of Boros artifact and creature reanimation that's slightly goofy but definitely you could play around ramming your spaceship Titanic over and over
