The AI in the arenas is every day more lucky with the cards he draws when he needs when he has exactly the mana to play them...
Very very lucky, so lucky i cant help to thiunk is programmed to be that way...
Whoever had the smart idea to create the Essences gear cards must be fired as soon as possible for having ruined definitely the few balance the game still had...
Problem is, in the long run, this game starts to get more unfair everytime, decisive cards only for paying (and theres an awful lot), imposible to beat decks (and the AI makes you play with them in Arenas, im tired of using a Light deck only to be stomped by the "destroy all light cards and heal yourself for every one destroyed" card), or those absolutely bully decks in the campaing that you only can beat BUYING with real money a lot of cards... A while playing this and you discover that the fun ended many duels ago...
Win this game is easy: be the AI and have Insatiable in the deck. AI is so bad programmed that ALWAYS starts in initial hand and plays at second or third turn.
Nitroeus is right: arena absolutely unbalanced. An is starting to have the same cards in all decks, why so many cards if everyone is using Seal of banishment, Vampire curse, Photon wyvern, Evolsaur darwino and Jinzo if they have it?
the system to select adversaries in random player daily is so bad that hurts, im tired of losing versus people 10 or more levels higher than me, cant it be more fair in level terms?
For heaven's sake, nerf the AI in the arenas...its annoying that he always draws 3 lightnings or whatever card he need in a row... make him a little more modest, please
