When will they make it possible to create a run only gifted Pokémon? (Google Translate)

[Celstiaone]

As the title says, it's about doing a run without capturing, trading, or buying a Pokémon from another player, and using only 
the Pokémon given to you during the run. The Magikarp from the salesman is allowed because it's not a trade or a player purchase.

 

I've already made several attempts, it's been over a year and failed because there were too few gifted Pokémon plus the fact that it had IVs of euuuuh to put it bluntly, dog [heck].

 

I don't want to spend my time constantly creating accounts because of RNG, i just tried again and I didn't even reach the first arena before the run was already over.

 

What ended this attempt was Growlithe Nature Relaxed, IV 01-11-08-03-25-15, obtained in Viridian Maze. 

This RNG on Nature and IV is just annoying because it makes this run attempt impossible.

I would have preferred it to be like my starter, Docile Nature, IV 20-20-20-20-20-20, and it's not the fact that it's a 
Growlithe that ends the run, but its nature and IVs are RNG on a Pokémon that I only get once.

 

I just spent another X hours leveling up Speed IVs on Route 1 (without buffs or items), and I was expecting to get those 
SPATK IVs up in Viridian Forest even though it would take a very long time.

 

But the moment I got the Growlithe, its nature and IVs instantly ended the run.

 

For those who say you can manage, well no, because IVs and natures can ruin everything, especially IVs on Pro, unlike on PokéMMO where it's not a problem.

 

Plus, on my previous attempt over a year ago, I had so few Pokémon that I couldn't even consider doing the Pokémon League, not to mention their IVs and natures.

 

Not to mention that I couldn't find any pro runs of this kind on YouTube, so the phrase "it's easy" or "I've already done it" is worthless if there's no proof to back it up it's just talk.

 

But from what I see even after several years it's still not feasible, I can't be bothered to spend another x hours on a run that's doomed to be wasted or I can't do the league because

of poke with nature iv RNG on gifter poke(abandon poke) especially when I only get it once.

 

So, to put it simply, "When can I play without RNG ruining everything, without having to create 50 or 100 accounts just to do and finish one run?"

I remind you that Google Translate was used to translate everything into English.
