When Metatron cast the spell Castiel wasn t afected, he wasn t cast out of Heaven , he was send to Earth. But probably because a part of his grace was used on the spell that is why he is not able to teleport and that is why Tamiel was able to teleport, he was on Earth at that time and he did not fall and has his wing intact. ( that is only a opinion )
