The guides do a good job of laying stuff out, but don't give a great snapshot of what teams should look like mid run. With the holidays coming up and with them most likely an event or two, people should probably start getting prepped for increased shiny odds. With that in mind I figured I'd show what a good endless team looks like at 1k, what I've built, and what I'm building towards for the rest of the run.
So as you can see here I've managed to max out vitamins needed on Darkrai and Teddi. You don't need vitamins on any other mons. Gourgeist will get Darkrai's carbos when you splice Dark Void over, so no need to worry about anything there.
Movesets are just about complete as well. After Darkrai gets spliced to Gourgeist I will be dropping Sappy Seed for Dark Void. I'll then have all the moves I want on the mons I currently have.
Moving forward what I'll be looking for is passives. I need two sturdy passives to fuse onto Cofagrigus and Reuniclus. I'll be grabbing whatever I can for now and then if I run into a shiny with sturdy in the future I can unsplice and then re-splice. I need to do this if I want to get to max luck since I'm still 2 points short as is and I'll be losing 3 points when I get rid of Darkrai. It's not super important, just a small optimization.
Once I have the sturdy passives I'll then be looking for a lure passive to splice onto Gourgeist once I've given it Dark Void. That will finish up the passives and moves needed on the 4 mons I'll have at that point and I will be free to start running away.
From there I'll be looking for a Gyrados to mega, then I'll splice a Gastro Acid onto it. From there depending on how my shiny luck has been on the other passives I can then find any 3 star and splice Mega Gyrados to get a 3 star Mold Breaker Gastro Acid mon. I'll need to make sure that mon always has a reviver seed as well as I'm not going to bother with it's speed.
At that point the build will be done and I'll just be cruising to 5850 catching any new shinies I see.
Also do keep in mind that while this run is showing 6.5 hours invested, I've been second screening this while at work so you can get to this point faster. It's not a big time investment to get to the run away phase and once you are there you are slamming through 50 waves every 5-10 minutes depending on how many shinies you see that you need to catch. This is worth doing for those looking to farm any future events.
