Regardless of what happens, it is going to be a battle fight sooner or later. I feel that struggle's kind just isn't taken into consideration for harm calculation, so it must be equipped to damage ghost forms. There is no way round it if you have no strikes so as to affect it, and it has no moves so that it will have an impact on you. If battle ends up not affecting Gastly, then it wins, due to the fact its struggle will certainly impact your Rattata, of direction, if in case you have therapy objects, you could just junk mail them in your rattata when the gastly starts struggling, as battle offers recoil damage. You just have got to maintain fighting. The enemy will run out of PP ultimately. Battle is type of a fail trustworthy on this regard. As it is going to put an finish to battles that would emerge as being incapable of ending because of situations like this. And fighting is the one thing that you can do. No amount of items will pace this up.
