Oh, no problem. I have the male Mawile now and with 3IVs, so that's a helper for later. But I need to know what nature you want on the Chansey? I'm going to try adding Mud Shot for myself (part of my plans), so you'll get that as a bonus. Once I level Mawile, I can breed it with the Chansey, then Ditto the correct nature in before working on IVs, though adding Mud Shot is just an extra step in between that.
Well, I just checked it. This will take a bit. Seismic Toss has to come from Mawile...and that is a chain breed. If I add Mud Bomb, that comes from Skitty...and is ALSO a chain breed. That one isn't a problem with many potential mates; however, I have to locate a Mankey/Primeape to give the move to Mawile, and that assumes I have the right genders on hand to start off. AND that Mankey/Primeape has the move.
I'll move this to tomorrow as I know Mankey is in my Bank. After I get the Mankey-Mawile pairing to give me a male Mawile, it's just a case of leveling it up and breeding with any Chansey. Same with the female Skitty, though male Skitty are harder to come by for breeding, and thankfully all Chansey are female, so breeding that phase is not an issue. It's just getting the grandfather and father on hand. LOL I'll make sure I have a female Mawile ready to go, and I think I have a female Delcatty to breed with to get a Mud Bomb Skitty.
n/p, just finishing my Kanto Dex. I'm three Pokémon away and also want to evolve my 5IV Rhyhorn/Rhydon and 5IV Seadra so they're over where they belong. Training in the Chansey Safari, but I'll pull one out from the PC for eventual work.
Sorry, been busy with other projects - for instance, in Johto, some can only be found one day a week and those were the last two days. I'll grab one of my Healer Chansey when I get on this evening and look for mates. I've also been doing some IRL stuff lately and haven't played as much, but the Johto projects are now complete, so I will only have to grab more on request. Mostly in X now.
Let me know whether you ever got that Seismic Toss Chansey. I've been thinking about putting that one together; that and another move (Mud Bomb, only other attacking move) as well. Maybe I can help you at the same time.
I have a Friend Safari, so the HA is also a possibility (Healer I think).
Regular Kyurem is still a better choice, as its slightly higher Special Attack means stronger STAB Blizzards. Kyurem-B's physical movepool is very shallow, as it doesn't have too many physical moves to take advantage of its 170 Attack.
