Form abilities are very obvious when they're happening, which other than Slow Start are the only abilities hard coded in the Legends games.
Though i do expect that Shedinja, if it were to be in a legends game, would also have wonderguard hardcoded, it would just have a visual effect to make it obvious it was being blocked.
