Um, she is very thoroughly aware of that, bruh.
Looking at the context of her post, you'll notice that she mentions "black moving first" and "Trick Room" in the same breath.
This heavily implies that while white normally makes the first move in chess, Radomus tries to turn that norm on its head. The color that normally goes last now goes first, and vice-versa.
In other words, slower Pokémon move first, and faster Pokémon move last.
See what's happening there?
