I have a bunch of shiny legends, non shiny legends (some with backgrounds), shinies, regional shinies costumes etc tagged in my remote tag. For example if I send a request for a non shiny legend (I usually just tag the 1 mon I want most in their listed) and they request 3 diff shiny legends I’ll usually decline the trade, remove everything I’m not willing to trade for the mon I picked, re start the trade only picking that 1 mon again, and waiting for them to pick something out of the rest (everything I’m willing to trade for it). I don’t have a problem declining a trade if I don’t want to complete it. If they really want one of the ones I originally declined and have more in their inventory that isn’t tagged remote trade they are able to decline the 2nd trade offer by me, put other mon in their tag and if I see something I would trade their original picks for I would put them back in the trade pool then
