>If we assume Piers' rare league card depicts him at the protagonist's age (very similar facial and body proportions to male protagonist and Hop), that pegs him at around 10>His rare league card mentions that his younger sister is a better pokemon trainer than him (meaning she had her first pokemon by the time he was 10ish)>Marnie's league card mentions she was something of a crybaby until her brother gave her her first pokemon (meaning she had a discernible personality at that point, so she definitely didn't get it as a baby or anything, pegging her at at least 3-ish, although she could be older)If we put all this league card information together, Piers is at most 18-ish, but even this would require her to be the youngest trainer in the series, given the preschooler trainer class is kindergartner in the original Japanese, putting them at 5-ish.
Given she's already shown talent as a trainer by the time of piers' rare league card and the youngest trainer are around 5, she'd probably be five or six around when Piers was 12.
Assuming the four gym challengers in Galar are around the same age as of sword/shield (~10), Piers' maximum age, assuming Marnie's a year older than the protagonist and started displaying talent in kindergarten, is 16.
