The Wally fight was unexpectedly hard. Everything was going well until Gardevoir landed a crit + Special Defense drop on Luna and then started Calm Minding when I switched. At least Wailord managed to do enough damage for Gardevoir to die to a Quick Attack.
Luckily, there is not much grinding to do before the E4. I may replace Wailord with Kyogre.
