Why Goku uses all the transformations he has except Super Saiyan 3 in the tournament of power? is there any reason why Goku uses all the transformations he has in the tournament of power except super saiyan 3? So far he has used,

Super saiyan . Against Caulifla for example.

Super saiyan 2. Against Kale for example. 

Super saiyan blue. Against the trio de dangers for example.

Super saiyan god. Against Dyspo for example. 

Does super saiyan 3 has a disadvantage over all the other transformations or something?
Because SSJ3 suppose to drag a lot of energy and it was shown when Future trunks came however I think it is not shown because we await for new form.
