Current Top 24
It’s been a while, but it’s that time again. What’s your top 24 look like nowadays? I recently maxed out the Mewtwo I caught from my first EX Raid back in February 2018, as well as Rayquaza, but I’m currently on the hunt for a perfect Mewtwo to add to my roster. Making some small progress with my Salamence, Metagross, and Snorlax, but they’ll get up there eventually. Also maxed out my very first Blissey a few weeks ago, who has been very useful to me for gym defending.

Here is my top 15. The Slakings were all caught Slakoths and just evolved (like someone else posted) without using stardust. I am thinking about powering up two more SB Mewtwo for taking down Mewtwo, however I think I have enough. I hate that I have a better Latios than Rayquaza as I caught over 120 Rayquaza. I guess I’ll have to go for another perfect Mewtwo. Fun fact: Mewtwo was the ONLY 100% legendary I caught up until Moltres Day when I caught a 100% Moltres with Sky attack.
Thanks. I just finished that Dragonite this morning. It has Draco Meteor so it doesn’t get used as much as my Outrage ones.
Next is that Groudon before I work on my Luckies: another SB Mewtwo, Rayquaza and another Groudon. All of them have amazing IVs as well, 93%+. After that, next goal is to try and get a Lucky Kyogre.
I feel like you’ll eventually get one. Just like how you waited forever for that perfect Espeon.
The Lucky Mewtwo took me forever it felt like. It was about 10 of them before the first Lucky one and was glad it had amazing IVs. Rayquaza took 1 try and Groudon was 3.
I have been having some insane luck with perfect IVs out of nowhere though. A few weeks ago, I even got 2 back to back from random raids. A Wailmer and a weather boosted male Kirlia.
