I have to say you are very annoying, but let me give you a scenario of the fight.
1. Gaara meets the mizukage they exchange blows and try to analyse each other.
2.Gaara overwhelms the mizukage with his attacks and is forced to summon his clam.
3.Off course when they were exchanging blows the mizukage dodged in order not to get hurt.
4. The clam casts the genjutsu and Gaaras attacks prove futile.
5.Gaara connects the clam to the genjutsu and places sand in all directions and senses the clam.
6.You might be wondering what the mizukage is doing all this time. He is busy using techniques that cannot pass gaaras defense.
7.Gaara uses sand to pull the clam into the ground and crushes it.
8.The genjutsu is dispelled and Gaara catches the mizukage with a sand pyramid.
9.The mizukage escapes using the Jokey boy and becomes weak.
10. Since there is no gold on the earth Gaara uses gold that is in the earth and uses it to stop the jokeyboy.
11.He senses the mizukage and traps him again with the pyramid of sand.
12.Gaara gives him a befitting DESERT FUNERAL or alternatively gaara SEALS HIM.
13.If after all this you do not agree then i am afraid i cannot help you.
