What to do with all the extra Mewtwo’s from Go Fest

In essence, what my title asks. What do y’all do with your “surplus” legendaries from Go Fest and similar events? I don’t really have a need for 40+ Mewtwo’s given I have 2 shinies and a Hundo. I have maybe 2-3 more I’d like to keep, but the rest are basically wasted? Do you just transfer them to Pokemon Home? Transfer to professor seems kinda wasteful 😂
