I like the invitation thing, but I can KINDA get where you're coming from with this? I'm just not really sure how you'd make a commonplace thing for the toys to life concept interesting or exciting for a fighting game trailer that gets the point across immediately, like would a kid buy a new toy/figure every trailer?
It is kinda funny that what was originally just part of Villager and Isabelle's trailers was expanded to Joker, Terry, Byleth, Min Min, and Pyra/Mythra, but considering its use in promotional material (like as placeholders for the Fighters Passes, being shown when they said more characters were coming), it's a pretty immediate way to get the point across at this point and I feel like it's likely to continue as a marketing/promotional tool considering Ultimate DLC expanded the invitation's role a lot lol
