Cute Charm increases the odds of finding the opposite gender. Lead your team with a male pokemon that has the Cute Charm ability, you will find more females. Lead with a female Cute Charmer, you'll find more males. I used a male Cute Charm lead to get my shiny female combee in Y, and to find a female HA heatmor in a durant horde so I could breed it shiny. It comes in very, very handy when you're trying to get females from pokemon with a very high ratio of males to females. Or male kirlia/female snorunt for their specific gender evolutions.
I'm up to 1,400 SRs for regice already. SRing a grounded target is soooooooooo much faster than soaring encounters.
@ Charoshi - lol that typo
So its kind of like Synchronize, only with abilities? Good to know. I guess that still makes Manaphy the undisputed hardest shiny to get
BTW guys, of the unobtainable shinies of Gen 7, which do you think is the one you most want available? For me, its Buzzwole due to its vibrant, watermelon-esque coloration
