TL/DR at the bottom.
As TCGs go, this one is clearly not llike the others, which is good and bad.
Pros: Quick gameplay
Multiple games at once
One of the easiest learning curves out there
New Campaign missions seems to be added every month (this is still a new feature)
The first and third win bonuses of the day can be gained EXTREMELY fast by playing against one of your own deck (filled with lousy cards for even better results) in the hands of an "easy" AI
Draft mode is an easy way to make yoursef new cards: Wait 3 days, pay the entry fee, pick the best cards for your future decks, lose 3 or 4 in a row and then you get to keep these cards. You could alternatively try to pick a winning deck but you risk picking cards that you already own the maximum of 3 that you will be forced to vendor after the draft for a very reduced amount of silver.
Cons: You get absolutely NOTHING when you lose
Normal ques matches you against everyone because there is no Elo (including those impossible-to-beat decks)
VERY hard to make resources (called Silver) outside of the login, first and 3rd win of the day bonuses
There is 3 settings for the AI, the hardest one being called Hard. This is misleading as they really don't offer any challenge whatsoever. The 3 settings should be called as follows: Foetus, Toddler, Pre-School
You stop getting resources after 20 wins per day. This game doesn't want you to play it too much.
The Draft pool doesn't have all the cards in it and its easy to quickly obtain almost one of each heroic cards from the available pool, after which you are left hanging if you would like to get some heroic cards outside of the pool (start being lucky with the random packs).
Outside of the real money (gold) options, the shop is very plain, offering at best 4 options that are not an insult to your mathematical intelligence, 2 of which are a one-time offer. You are left with packs or legendary chests to buy with your silver, the chests cost 100 000 and you get 250 per wins. You can never buy a chest more than once every 10 days that way, unless there are some specific tournaments that rewards with more silver than you paid to get in.
TL/DR: I really like this game's gameplay and I really feel like the shop could use a MEGA overhaul. The sad thing is that the game tends to make you not want to play more than 3 games per day (and to play them against the computer) because of how the resources are rewarded.
