a template is the better option, ofc, but even then with tilting the rack, put the rack above or below the spot, set the low balls where you want them, etc. you can achieve some rack mechanical advantages
Yep.
In 9 ball with magic rack:
Rack balls ~.25" lower and the wing ball will go even easier but, the back (where 2 usually goes) will have a wreck more often before it gets down table. Plus, with rack lower, the 1 ball is more out "not" to go into side pocket....and to me, thats a plus. That way you know for sure where the 1 is gonna be.
Move entire rack forward and your opponent will not make the wing ball....period. however, the 1 ball will go in side more often.
In 10 ball and magic rack:
Move entire rack up table ~.25" and the two balls behind the 1 ball goes much, much easier to side pockets....unless the felt is new or balls are polished....if thats the case, they will go WWWAAAYYY long past sides which means push the rack back instead of up to adjust.
Tilting the rack is hard to do and not get caught so, I don't normally expect that to happen but, I do play several people that "try" to move the rack around to affect the layouts.
All that tells me is they are scared or they wouldn't do it.
