Decks are out powered and that way new players *normal* decks hardly win games, maybe...
When you are new player, you dont have much cards, no power cards ect. so if you fight many fights, like I did almost 100 (I think) and you lose most of them, its not fun game or is it? I'm not good player and I dont even want to be. I had few good fights, they was good games, I lose, but its ok, good game is good game, even you lose, but most of games, enemy run over me, because enemy own really strong deck. Ah.. that idea.. You have many standard decks, 30? so maybe, if you do one option to play those decks, standard cards, random deck. When you click random game, its take one of those deck and enemy got random deck too, standard cards. This way you really need to know how to play, decks are equal powered. Maybe 2 land decks, so there is lot of changes to got different cards every time. Every game you got new changes for lands and cards, you really need to know how to play. ofc. this is not good for players who feel that they know how to play, but they just pick strong cards and win games that way. Random play, random decks,land,cards, you dont never know what you got. That is fun, maybe... but at least, players are equal for decks. If you make deck powers mostly equals. Hope you understand what I try to tell lol
