Why don't you get Magic Workstation? You get all the cards and everything Apprentice has to offer, but instead you get better interface, an always available and ready-to-play user base, and, best of all, you get all the card pictures.
In other words, Magic Online is a good thing – if you like to be ripped off. Apprentice is a great thing - if you like playing without pictures.
...as for the rules "problem" - that there are no actual rules programmed in either Apprentice or Workstation - well, it would be indeed a problem if you encounter many that can't play. I've played at least 100 casual games in Workstation in the past 6 months now, and rule issues only came up once or twice, and they weren't any issues that halted the game at all...
