[quote]As you said Goku is not known for being smart He'd pass off the oracles as nothing and be wiped from exsistance[/quote] When it comes to combat he is. And guardians can only do it after knowing what to do. After dying over and over. If goku used his mind reading on a guardian that already went in he could do it easy. And goku is hella smart when it comes to fighting. And he could kill them with a 360° energy blast like cell does. It would probably kill them all in a flash.
