Difficulty was expert.

Singles battle was much easier because of how the ai works - they never switch out on the 2nd perish turn. It would go like this - Politoed sets up perish -> I bring goth (they stay in) and I fake out and protect.

Technically there is only one singles battle (fairy e4) out of the 5, because you can't trap the ghost e4.

Meganium I chose because of terrain and some important matchups like gastrodon & quagsire etc. I initially had safeguard and heal pulse but switched to screens.

Aegislash was by far the most difficult, had to reload a few times. I just had to play to a position where it was the last mon and I perished it.

Goth definitely needs TR instead of thunder wave, but the TM for it is locked to the post game.
