Incineroar 7 Star Solo Tera Raid ~ fainting as a strat??

Contrary is a heck of a drug...
I had to think about this one a little bit.
But if you have Contrary at the start, you get buffs; then you skill swap and the boss de-buffs himself; then you build-up tera as HP gets lower...
...then faint on purpose... (?)
Then you come back and your Contrary ability is back - so you can finish him off with a move that should debuff you... but buffs you instead...
...Contrary is a heck of a drug...
Anyway! the whole fight is here so you can see how it worked for me - maybe it'll work for you too! What a weird way to fight a Pokemon battle. LOL
Get yours!!
