Same here...its just the algo making it difficult for us. Ive lost I 5-6 battles so far and the odds as you know are 1/4 with a high level counter so its just going to take time until the algo allows us to beat it.
Up to this point I think I lost two times in total so I am not too mad about this one being difficult. I would not use the ultras, there are the same percentages with some other options if you get what I am saying. No need to use dragons you need in the next few rounds if possible.
