This game has a pretty original concept. Sure every new CCG will be compared to MTG but I think a direct comparison is difficult in this case. Since Spectromancer is a lot more versatile than most other Trading Card Games it opens new perspectives.
Despite being innovative this might cause some problems as well. Balancing becomes more difficult the more complex a games gets and introducing all features while remaining simple enough to allow beginners a smooth start can be difficult to achieve in more advanced games.
However, Spectromancer is an easy to learn game that offers great in-depth strategies and combos for advanced players at the same time. Talking about balancing, everyone has a different oppinion. Obviously some cards and combos are clearly superior to others but finding those combos is what makes a good player. The overall balancing is at least satisfying in my opinion, although not all the character classes seem equally strong to me.
Pros:
+ new concept
+ many different classes, each with a full set of cards
+ polished campaign mode with nice character customization
Cons:
- only a limited amount of cards for the basic elements
- difficult to balance all classes to the same strength
- not all cards available for use in your deck
