Pros
Pro Near-perfect balance between going first or second
There's no significant first-turn or second-turn advantage in Hearthstone. The player going second gets an extra card from his deck as well as "The Coin", a card that gives one extra mana crystal for one turn. This subverts the advantage that would be gained otherwise by the player going first.
Cons
Con Huge money sink
Although you can "technically" play for free, Hearthstone is very stingy on rewards. To get the limit of 100 paltry coins free a day, you have to win 30 games vs mostly players who have much better cards than you. It can take a new player 6 to 8(or more) hours to accomplish this. And after all this you get a pack of 5 cards that are often completely worthless to any viable deck. It's possible to get cards like "Angry Chicken"(worthless card) as the "Rare" card several times. You can also get a bunch of cards you already have a lot of.
Con The reward system is not significant enough
Hearthstone's reward system is very lackluster, providing little to nothing of significance to the casual or excessive player. There will be times when you feel heavily rewarded by the game, but these times are few and far between and if you are driven by rewards you will likely lose attraction to this game quickly.
Con Poor port
Plays much better on PC. Sluggish and crashes often on mobile, sometimes connections can be difficult to make as well.

Pro You won't be cursed at in the chat
Interaction with opponent limited to simple pre-made phrases, so you don't have to see how many 1337 gamers had their way with you or your mother. Or deal with the spam about free decks, new hacks etc.
