Quantum's Take

Zatanna is one of the best supporter champions in the game, especially since she can actually deal a little bit of damage on top of being there to super charge your Constantine. You will hear a lot of people say that she doesn't require a lot of investment, and while it's generally true that she performs well enough at low blue stars or even 5 white stars, getting her to purple stars or better will really ramp up her kit. In my book, she's a certified Whale, though you can get away without buying her legacy piece if you're a non-spender or lite spender.
