gaara also uses clones as well,his sand clones useless?,a single one was able to fool and resrtain the mizukage after taking the shape of onoki to trick him,another one proved tough enough to hold it's own against joki boy long enough for gaara to get gold sand,itachi's clones are actually more useless in the show,and the clone exploding wont bother gaara,seeing that he handled an explosion that levelled a building when he was 6xd.
Water>sand?,r u joking?,gaara put his sand into mei's water dragon tech,and stull used it easily to hold madara,sorry,but water does nothing to his sand.
How many clones can even itachi make with his pathetic levels of chakra?,and then go on to use ms jutsus. IIRC when he uses his ms jutsus 3 times,he turned off his sharingan completely,and gaara has sensor sand which can easily detect the real itachi while gaara leaves his superior sand clones which have more chakra in them than itachi's owns and can regenerate to deal with the fakes.
LOl at totsuka breakng sand sphere,when an ems susanoo couldnt break through a small sand shield that was put up without gaara even looking at the susanoo,what long range tech does itachi have that can hurt gaara?,and gaara would still attack itachi in his sand ball which would be in the air.
I have already seen the kage summit arc,and gaara blocked 3 entons like child's play,would have broken sasuke n half if sasuke didnt form the bigger version of susanoo,gaara attacked with sand drizzle in thet fight. Gaara can easily take advantage of the under opening of susanoo which means itachi os a dead duck,not to mention itachi can't even hold his susanoo for 5 minutes b4 dropping dead LOL. Itachi is the one who can't scratch gaara
