I think this game is not any good for begginers or occasional players.
I've tried it for a while now, and been totaly fed up and disolusioned with the experience. Yes it should be a good game, yes there should be lots more joining, but in game where major and senior players can manipulate the level ladder so blatlently it will never flourish once players are aware of why they make no headway in the game, and many players realise its not going to work.
The problem, despite what players who do it will admit, is going backwards on the ladder. I have been paired up with so many players on the ladder doing this that it shows its not an anocasional thing but prolific, and when you multiply that number by the numerous accounts they play, the game only goes one way, down.
I have met multiple players that have played me at level 20 and all levels as you try to level up, that have been playing for 4 years, they have leveled up to level 0 and maybe higher. They have all the knowledge and cards and decks from all that leveling up that authentic players have little chance against them, and no matter what any player tries to say losing sll the time is no incentive to play a game, you move on.
I have sent in to support, and included screenshots showing its happening, but it looks like they re happy to keep to the old player bloodline. Shame really it should be great concidering its beginings, but a cheat will always find a way.
