Lucky junks

Low level is ok, since lucky pokemon have lower stardust cost then normal. Low IV is really sad, and I think those are the ones needs to be transferred. But 15 out of however many pokemon storage isnt that many

I have been asking myself the same question, I think I will start deleting my junk luckies, unless they may have some added potential in a future community day.

I made some interesting observations today. I did 18 long-distance trades for the double candy. The News text from Niantic is confusing, candy is still obtained by sending not receiving. Three of the 18 trades turned lucky, all three involved trades with Mons from 2016 (2) and 2017 (1), of approx 6-7 in total. Low numbers but none of the trades involving recent 2018 Mons turned lucky. My partner was extremely happy, he got a lucky 98% Body Slam Snorlax from me, originally from 2016. He also got a normal 100% Mon, a level 19 Caterpie. This is the first perfect I have seen from trade, it will stay in his box since it is perfect..

An annoying bug I have also observed is that several Mons are not registered with location, among them some of the first legendaries obtained by research breakthroughs. They still only yield one candy obtained by trade, not good.

I have 64 luckies, going for trash and important ones. Haven’t thrown any yet but I will. Example: this morning a 75% 704 Roselia and a 75% 849 Ariados. After I get a lucky I generally stop trading for one, though. However, I have enough room, even though I can carry just 1000, not 1500. For me game is on a swift/steady downslope, so I trade and throw stuff out all the time

I think the answer is clear, trash must be thrown away.

How can a lucky pokemon be low iv?

Just this morning I started trashing Lucky Pokemon that have really bad IVs, if it's a Pokémon I wouldn't consider using for any sort of battle.

I now evolve, then trash those that had less than 85% iv.

Muk, Golduck, Noctowl, Ninetails, Kabutops, hatChu, Parasect, Jynx, Aggron, Quagsire, all got trashed today and it felt good.

Yeah, when trading for candy, the quality of the Mons varies a lot. It is much easier to pick a bunch of Mons when on travel, and use them for trading when you come home, than finding another trainer from a distant location.
I am not even sure I will keep a lucky level 20 Beldum with 11A 10D 10S or a level 22 Ralt with 12A 13D 12S. Candy are scarce for both, and I would rather work with better IV variants.
