We have not made it too hard early on,I think at your level he is mainly restricted to commoms and uncommons.You are on AI level 2,It goes up to level 24.Many people have found it too hard at first, but experianced card gamers may find it easy at lower levels.Later on power cards come into play which also make it tougher.
However if you want more of a challenge I suggest trying the glassboard app and adding yourself to the spellcraft one.You can ask for opponents there .Details are in the link above.
Or maybe someone can add their name here for Molotch to play against.
Sorry Mark, I can see how it may have read. I was being honest and not derogative (just reading some those Q and V posts can leave you feeling a little insecure). I was just trying to see if my start with the game was passable:)
