Tangrowth DP7 VS Dusknoir X Stadium

[Brybry]

Good afternoon !
I have a question for the Poke-Body of Tangrowth SF and the stadium Dusknoir X :

The Poke-Body of Tangrowth is "Remove 1 damage of Tangrowth beetwen turns". My question is : What do we do first ? Use the effect of the Dusknoir stadium or use the Poke-Body of Tangrowth.

Thanks for reading ^^.

It doesn't matter.
Even if Tangrowth only has 10 HP left, all effects have to be applied before you check to see if there is a KO or not.

In cases where it might matter (say if Tangrowth doesn't have any damage on it yet, then the owner of Tangrowth would get to choose the order.
