Ziva is the obvious first answer here. A full 4-7 evo has just short of 40k attack. Even the base at full advancement has well over 20k. With the added bonus of being free to acquire, Ziva should probably be one of your first acquisitions for a magic based deck. On the downside her skill is Divine Storm, and while that is not useless, it doesn't help the rest of your deck. Still, with her insanely high attack stat, it doesn't matter.
