In terms of a digital TCG, I am not sure there is any real competition on the market. Most other games are CCG and, as such, the time you spend playing those games does not accumulate any value. In a TCG, your cards have real world value.

If you want a solid trading card game, your real choices are Hex or MTG online. Hex is cheaper, not tied to a paper format (it can use digital mechanics that cannot exist in paper form), and has a better player experience overall. As you can see, I have sunk many hours into this game--being able to play for real money prizes every week without worrying about getting dressed, driving, or dealing with the impracticalities of hundreds of people being in the same room is a huge bonus.

The combination of it being a TCG, your collection having value, and being able to play for cash prizes weekly is hard to pass up if you are serious, competitive card player.
