I am already planning to try Vivi out in my Izzet prowess deck, which will either pop off, or get removed on sight
Some cards have group hug potential too, where you actually give players something beneficial in exchange for a personal advantage
But even without ever using that ability, this is like a two-mana Scroll Thief, but instead of drawing just one card, it draws cards equal to its power
Whether removal, card draw, or something more esoteric, you can have a lot of fun with this one
It does cost one mana, and it can eventually grant double strike, but that's stretching all sorts of boundaries and definitions
Prismatic Ending is an example of a card that takes advantage of your ability to produce five colors of mana
