The argument is closed, no need to be stubborn about that. Take this like a second warning (the first one being "be nice to everybody or just leave them alone"), I deleted your answer, next time I will have to block you for the obvious reason of you entertaining a bad mood in the forum. We're several to be harsh one time or another, the thing is to not insist with this, okay?
You wanna focus on your own Morty. He can only learn sronger and stronger moves, so the more you will level him up, the more he will be useful. However, do NOT use your Levelup Mega Seeds, because once you'll get Egg Morty (Got from a stranger found aftr beating 2 council members), you REALLY wanna save as much LMS(Levelup Mega Seeds) as you can. You know Magikarp?
It starts out at level 5 and evolves at level 20 into The One True Morty. It's very good, it knows only one move called Ascend, but it haves a power of 120.
Your Morty haves extreme stat increase, so if you get Attack/Defense/Speed Mega Seeds, use them on Morty. Attack Mega Seeds give 10 ATK, DMS give 5 and SMS give only 3. You wanna use SMS on the Mortys with the least speed, because they're realy not worth it. Fill your Morty with AMS because he can get easily deadly. Defense, well, he doesn't have the best HEALTH grow, so it can be a good idea.
You wanna put Scraffy Morty on your team (The first Morty you get) and evolve him ASAP for rock types. Big Head Morty is also a good replacement, if leveled up enough and evolved. Scissor types, Double Morty/Exo-Alpha can be good. Remember to evolve them. Paper types are the rarest for me. (Colour) Shirt Morty is a VERY good idea. They have 6 forms, so it can be very thrilling if you find the first form and slowly scale up to the sixth: Rainbow Shirt Morty. Cold/Hot Morty can also be somewhat good.
Their evolutions are beast.
Burning Morty can learn Fireball, a 5-times only move which haves a power of 150.
You can evolve Mortys by finding 2 of the same Morty, if it can be evolved.
Now, if you find somewhat a special morty who you think can't be evolved, like for example Hammerhead morty or Cowboy Morty, Don't even try to use them. You want to have VERY high levels. If you see that a certain Morty is common enough AND can be evolvable, Catch it with a Morty Manipulator Chip. You can either buy them at Salesman Rick's, Find them at Blitz and Chitz or trainer battles or craft them at the Crafting Stations.
Oh yes, i am obiviously better than the wiki, so feel free to ask me anything, included crafting recipes and quests.
Status Update: I just got Egg Morty. I handed some guy in a blue shirt a Dark Energy Ball, and I received my Egg Morty. He's at level 10, and I have 4 Level Up Mega Seeds in storage, so as soon as he gets to level 16, he can evolve.
I evolved my Hippie Morty into the extremely badass Off The Grid Morty. His only attack, Green Blur, has a power of 100 and 8 uses. His stats are extremely high, as well.
I beat the 3rd council member, but his Multi Morty gave me trouble. Currently trying to find a wild Tank Top Morty so I can evolve him.
