I think if you personally feel satisfied with what you're doing, go for it, regardless of the method. Legit hunts for rarity factor, injecting to get something that looks nice for battles, or RNG abuse to search/catch for a mon without being at the whim of the ingame clock's slot machine, it's all on how YOU value them.
Personally, I do both RNG and regular stuff. I don't like modern gens, but being able to get mons with good IVs and ball types being passed through breeding was a nice change for people who wanted extra cosmetic factor and usable mons beyond being trophies to fill Ranch. Still, sometimes hatching eggs in Route 34 is nice.>>45624602Not how it works, the Cute Charm exploit runs off the Trainer Shiny Value (the combination of your TID+SID) being in the range of what PIDs Pokemon are generated from Cute Charm (unlike Gen 3 or later gens, PIDs from Cute Charm are all static, only changing depending on gender ratio or nature).
Certain combos exist though, and you won't always have an "ideal" Cute Charm ID, for example, one Cute Charm ID combo only gives you 2 Natures out of the 25 that exist (Hardy and Lonely), and some only work depending on the gender ratio of the mon you're looking to get (like an 87.5% male gender ratio would be the only one to work if you had a certain type of TID).
The best TID combo gives players 8/25 of the natures to be shiny, giving female shinies (since the Cute Charm IDs for a male CC mon lead/female wild was always the same regardless of ratio). Since Cute Charm mons had possible high IV spreads, it originally caught people's attention because the exploit allowed people to get many high IV good nature shiny mons in one save, since normally you'd either have to have a different save for each strong wild shiny, or settle for normal palettes, but the benefits are still pretty clear even for normal playthroughs.
You are right that getting the correct TID combo is ridiculously low though.
Happy hunting, guys.
