Personally i like that to be a mistery. later on i notice a name and enjoy beating someone much better ...... or feel less bad after being dispatched
Its not because you have a high level that you will play with strong cards.
Your level reflects how long you have played (points won during play) and not how good your deck is.
If the level was showed lots of low level players would refuse a challenge from a high level player, because they wrongfully think they will loose the fight.
