Pros
Pro Large variety of gameplay and formats
Between the cash tournaments, the ladder with rewards for both limited and constructed play, draft gauntlets, sealed and evolution gauntlet, as well as the single player campaign, playing the auction house, and the 'sandbox' Frost Ring Arena, there is a lot to engage in.
Cons
Con Questionable long-term viability
At this point, hard to see the game ever really taking off. Balancing and card development is increasingly questionable, especially in limited formats (such as the current set emphasizing RNG in the Conscript mechanic as a game decider). The game developers have essentially conceded they can't deliver much of what was promised on the PvE side while also struggling to translate efforts there into income.
The client interface (e.g. chat, auction house, etc.) remains atrocious. Multiple featured tournaments have been compromised by bugs. This seems like a classic case of reach exceeding grasp, and investing heavy resources into the game is probably not the safest play.
