Okay so it's cool enough and all, but damn this game is is like 70/30 pay to win.
You'll get plenty of cards. You even have a few chances to get some other goodies like card sleeves and so on. But honestly unless you're paying money, you just won't win except for a bot or two. But on the plus side, the card packs aren't expensive and when you upgrade the cards, it is noticable in a small way which builds to the more you upgrade them.
It's a TCG where you collect various cards based on various myths, superstitions, folklore, urban legends and so on. And that's pretty cool. Even better is that each card has its lore, it's cultural and/or religious backing, geographical information and so on in case you were ever curious about the story to something like the Wendigo or even something like Hades or the Kelpie.
The music is okay. Nothing great, but okay. Gameplay is interesting. You go back and forth in a tug of war like battle system where you cards will fill up a circle in the middle. At the end of the game, who ever has the highest total power remaining in the circle thing, wins. But the individual cards all offer something like increases or decreased power, mana cost, and things like situational triggers or tribes.
