The good: sounds, artwork, animation, card-stat dynamics, and a very clever set of insanities.
The bad: no real card interaction (e.g. creature enchantments, counterspells, etc.), no real bluffing or outthinking, a buggy AI (especially regarding discarding and xenophobia), and inflated higher-level stats that make creatures attacks and tainting pointless.
Overall: A very solid 4-star game that, like many of the card games here, could be 5-star with some work.
