Duelyst - very similar to Heartstone and Mojang Scrolls.

My top.

Positive:

1. Queue time when I usually play are nonexistent.
2. Easy to get into hard to master.
3. Alot of unique card special abilities. On death triggers etc.
4. Art style.
5. Small download.

Negative:

1. Each class is so different from one and other that its hard to predict and build a counter.
2. Its still in alpha so alot of stuff changes.

As always everyone says, there is no harm to try it out.
