So after Moltres Day I mostly took a break on trading as I was waiting out for Best Friends with
@nmihal and another friend of ours.
September 10th though, I did get a Slugma, evolved into
Magcargo 943, while doing a single daily trade to raise friendship.
September 21st: Hit Best Friends with nmihal and we went pretty much overboard, emptying out most of our reserves
Muk 1081. Traded as Grimer from the Kanto event, 98% 15/14/15, immediately evolved. Power up not as likely anymore considering Poison's only major utility was VS Fairy in GO, and now MM Metagross has eclipsed everything.
Magmar 1636, 84%, planning to evolve when Magmortar becomes available.
Gyarados 1665. Traded as Magikarp from the Kanto event, 91%, I actually used 400 candies on this just to get a Lucky dex entry on Gyarados, since I've already maxxed out 3 (2 100% and 1 96%) plus my Kyogre, I don't really have use for this.
Haunter 1285, Traded as Gastly from the Kanto event, 84%, did not fully evolve as I was hoping for some legacy/exclusive move Gengar event for Halloween/October etc. Might evolve eventually, power up not as likely considering I already have a maxxed 100% Gengar, 3 SB Mewtwo and 2 98% B/C TTar.
Charmeleon 673, Traded as Charmander from the Kanto event, 96% 15/13/15, did not fully evolve in hopes that Blast Burn will somehow be available on Charizard again. But even then, might not max out as I already have Moltres + 4 BB Zard + Entei
Sunflora 1772, Traded as Sunkern saved from the Johto event, 84%, evolved for the lucky dex entry, just collectible with no practical use
Graveler 1651, Traded as Geodude from the Kanto event, 87%, already had a Golem so I'm going for a lucky living dex here. Golem's somewhat obsolete of an attacker by now, after all
September 22nd
Tangela 1246, from the Kanto event, 91%, will probably evolve when Tangrowth becomes available. Might not see much use as a Grass attacker, however.
September 23rd
Snorlax 1799, from the Kanto event, 91-93%, 13 or 14 Attack IV. Nice to have around but proabably won't power up, not a fan of using Stardust on defenders plus I've got a 98% with Body Slam that takes priority, if I get enough Candy and feel like spending the Stardust... yeah this is gonna take a while.
Blastoise 1863, traded as Squirtle from the Kanto event, 91%. Decided to evolve this one fully as I really like the Squirtle line and holding back in hopes that HC returns still doesn't have much point, considering HC Blastoise unfortunately still isn't remarkable

Chances of maxxing out almost zero, just like having it around.
September 24th
Dewgong 418, traded as Seel from the Kanto event, evolved for the lucky dex entry, probably going to stay as is forever.
September 26th
Geodude 159, yet another Geodude from the Kanto event traded in, 96% but stays Geodude for living dex purposes.
Grimer 201, 82-84% 12 Attack

Stays around as Grimer, probably never getting evolved powered up unfortunately.
September 27th
Grimer 823, yeah we traded a lot of Grimer from the event those days, 91%, stays Grimer for now.
September 28th
Gastly 192, traded during the event, 93% 13-14 attack IV, stays Gastly for living dex purposes as I got Haunter and Gengar I'm waiting out for.
October 3rd (we had a little trade lull because of lack of storage/coins to buy more storage)
Aggron 2703, this one was cool, traded in as Aron, immediately evolved. It was my highest CP lucky for a while until Metagross outclassed it. I already have a maxxed out 100% for gym use so it would never get powered up anyway, but just having it around is nice.
Rattata 129, 91-93%, stays as is for living dex purposes as I already got Raticate
Exploud 1916, traded in as Loudred (this is what I get for accepting in others' mass evolve fodder lol), evolved, 89%, probably never gonna powerup
October 4th
Lairon 841, traded in as Aron, evolved into Lairon and staying in that stage for living dex purposes
October 8th
Ralts 141, from the Psychic event, 87% 12/15/12

Not too good but still a Lucky Ralts, it might get evolved and powered up eventually, I'd rather wait out a potential CD. It's female, so no Gallade option.
Alolan Golem 2146, 93% 14/14/14. Despite the initial shock of Amazes-HP-Attack-Defense-ARGH NOT 100%, this was pretty cool. High level Alolan Geodude traded in, immediately evolved... might even get powered up if I really need a #6 Electric attacker too soon (after Raikou-TS Zapdos-2nd Raikou-CB Zapdos-Lucky Jolteon). But considering Electivire/Magnezone are coming too, it might not...
October 9th
Grumpig 101, traded Spoink from event evolved for the dex entry, 96-98% 13-14 Attack 15/15, unfortunately these IVs are not really gonna shine on a low level Grumpig
October 11th
Alakazam 972, traded Abra from the event evolved all the way, 89% 14/14/12. It might get powered up if I need Psychic attackers, for lack of better.
October 14th
Mewtwo 2227, so I had an Ultra Friend who asked a favor to try out a Mewtwo trade for the Candy, and I accepted. It ended up being lucky, unfortunately 82% 13/12/12 (this is as rare as a 98% meh), probably not going to power up, I care way more about the Rare Candy than the Stardust when it comes to legendaries to justify going for low IVs just because of the halved dust cost of the lucky (bonus negative points since I do have a weather-boosted 100% waiting too!). Still, second lucky Mewtwo
October 19th (another lull because I didn't have much storage/coins to buy more, pretty much):
Corsola 706, now this was a cool one, lucky regional from Dortmund

From an Ultra Friend who did attend the Safari Zone there and is using them to get +3 candies and Pilot medal distance.
Shroomish 600, nothing really remarkable about it, already have a lucky Breloom I don't feel like powering up, a maxxed out 100% Breloom, a 100% Shroomish... it just stays there.
October 20th (in which I trade pretty much my entire storage out to nmihal to empty out space for Beldum CD)
Prinplup 722, now this is nice. I did try out my luck with the Gen IV starters and got this, 96% 14/15/14. This is getting saved for its eventual CD (might be a year away, but still! Lucky 96 HC Empoleon, count me in!)
Arcanine 463, traded in as Growlithe, evolved for the entry, not getting powered up
October 21st: This is the first time EVER I hit the trading cap of 1 Special Trade (Shiny Beldum for Shiny Beldum) and 100 regular trades (Beldum for Beldum), all with nmihal (who was an MVP trade buddy for this one, my online public thanks man you're the best

)
So, out of these 101 Beldum we got 5 luckies (I do believe the chance is 1/20 for recently caught Pokemon, so it seems quite average). Of these 5 luckies, the 96% I evolved into Meteor Mash Metagross and maxxed out (my #1 Steel attacker of the Top 6, the other 5 are level 30ish but not lucky), another became Metang for the living dex, the other 3 stayed Beldum. Apart from the 96%, everything else was 91% or less. And the full list is:
Beldum 135/110/85, Metang 784 and...
Metagross 3623!
I absolutely LOVE this maxxed out 96% Lucky Metagross. It is pretty much the first and only time so far that the feature of Lucky Pokemon has proven to be extremely useful meta-wise (Jolteon doesn't really see use yet) and great for collectible value. Were it not for it I'd not have any good IV Beldum to evolve for Meteor Mash, let alone max out at half the dust cost, and have a sparkling background to make it seem special in my Top 12
Anyway, onwards to:
October 22nd:
Beldum 357, 93% 15/13/14, this is from the "residue wave" of Beldum trades, ie the ones past the 101th we could not trade in the CD's day and just went for the next day, just for the candies. Still a collectible lucky to keep around, but it did not even have a chance to get evolved, not that I would.
Banette 1222, 89% 15/13/12, traded in as Shuppet and evolved for the entry, probably won't power up ever; when Banette was first released about a year ago from now I was considering it for Alakazam solos: 3 SB Mewtwo and 2 maxxed out 98% B/C Ttars later, no thanks
And today, October 23rd, I got quite lucky with the luckies, scoring 6! And a 100%!
Azumarill 288, traded in as Marill and evolved for the entry. Stays as is.
Skarmory 506, stays as is.
Cloyster 619, traded in as Shellder and evolved for the entry. Could max out as Cloyster is still a viable Ice attacker... but not for long, Mamoswine is coming. So no.
Bibarel 1116, now I had a lot of fun with this

Being Bidoof day and all, I really wanted to roll a Lucky Bidoof considering we had lots of spares to trade around. And I did. And I evolved it. That's all, I don't mind, it was fun
Linoone 1051, this was traded in as a Zigzagoon, and it ended up 100%! So it also doubles for my 100% collection. Evolved for the lucky entry and the 100% collection. Probably never getting maxxed out though, shame my 100% luckies end up being common things like this and Pidgey.
and finally,
Venomoth 375, traded in as Venonat and just evolved for the entry.
