Then..It seems you are not paying properly.Blastoise will do its job at level 74.Next time remember not to cross the level cap.As Steffo suggested use some Common candy on Arcanine too.
Maybe you can use the Exp. share on Beartic.That will be good training for him.You can start will Ampharos,it can hit both the mons.
I think Donphan will be better with Sturdy.
Don't be disappointed if you fail the first time, try again..you have a great team.
And I don't know why but can't upload the save files.
