After trying for a huge number of hours on some of the wizard goals, here's the one's I've found that are a bit easier to get to finishing off: 
 Gorgar, Black Knight, Whirlwind, Firepower & Space Shuttle
 
The rest of the wizard goals on most of the tables you might get after a while of playing it though it is roughly dependent on how much the table is in the mood to screw you over. Once the basic goals are done I found it's been easier (with the exception of lighting up all the different modes) to just go off how good the first ball is going. If it dies too quickly it might be easier to just restart it if you want to skip past all the crummy playthroughs to get to the good gems.
 
Most of the tables with the exception of the Arabian Nights aren't too bad on the basic goals. I found that when you start if you jump into the tournament (to unlock the Jive Time machine), you should be able to get most of the basic goals once you get trhough them all & unlock that table. Just my thoughts on playing this & hope some of it helps as this is one of those pinball collections that I feel has the best physics on recapturing playing these tables in real life, hoping there's a sequel as there's tons of other pinball tables from Williams (Twilight Zone, Monster Bash & plenty of others) that I'd love to play again in this format on the 360.

Space Shuttle is the easiest wizard goal for sure.  Gorgar and Firepower aren't hard either.
 
Funhouse wasn't too bad, and I just need one random thing to get Taxi wizard, so that one is just one of the more time consuming.
 
I'd love to see more Pinball games with authentic tables from these developers as well.

Ditto, aside from Medieval Madness (needing 3) all the rest I have that are left just have one very freaking damn challenge left that for some reason or another I can't get. Wish that they had a system set up in place so if you get one of the wizard goals while playing in the basic goals it would unlock those individual goals when you finish off the basic goals.
