Pay to win
Good concept and enjoyable game. But, its a pay to win game.
It gives you barely enough to come close to completing objectives that you can earn legendary monsters and then throws the paywall your way so you need to buy extra coins/tokens/time etc to get what you wanted.
This game is generally won by using your credit card more than anything else in game.
