Can I beat Pokerogue with only Giratina?!?!?!?!

I've been pretty obsessed with Pokerogue lately, this fanmade pokemon roguelike. I've amassed a lot of different Pokemon, including the legendary Giratina. Now I take the role of a commander of distortion, to see if I can make it through an entire run in classic mode with only Giratina on my team.
Rules:
1) Unlimited retries! I'm not trying to torture myself here, I just wanna see if I can get to the end.
2) I can only use Giratina in battle. However, I may catch a shiny or a legendary if I see one, as long as I release it right after. Cmon, they're too rare to ignore!!
3) I have to have lots of fun ^^
