Duel requires a pearl and is dangerous for the caster. Control does not and is not.
Furthermore, CB 1.41 doesnt exclude magic duel; it gives yet another option for dealing with magic beings.
Btw, poison golems cant be magic dueled, yet they are very much controllable.
Magic resistance fails surprisingly often in real games. In Querty, I've seen Devils fail MR 25 on the second check or so, twice in a row. So when you have a whole communion of lizard shamans spamming Control, there's a very, very fat chance all your magic beings within melee range will happily desert. Good luck fighting with markatas without supporting thugs.
