Is this just the Unova Dex, or are you including the National Dex? Most of the babies I already have are National Dex (such as Torchic, Charmander, Baltoy, Beldum, Drifloon, Mawile, Hoothoot, and so on). One exception that I mass-produce is my Zorua breeding project.
As for those five, none are immediately in my PC, so I can quickly breed any three of them. TBH, I'm planning to breed the Pansage/Pansear/Panpour trio from my Simi trio and import them to White 2 instead of catching them (they are shaking grass finds in Lostlorn Forest, and I remember the pain I went through finding the two I didn't receive as a gift; Pansear took FOREVER to find at Pinwheel while I found multiple Pours), so if you want to make two of those three (Pansear and Panpour) import candidates for the Everstones, I can have them ready to go. You might even get Egg Moves with them if I find something with STABs and/or powerful (and if I have females to start with). :)
That leaves a matter of preference for the third; Tirtouga, Alomomola (that's a palindrome BTW), or Rufflet. If you prefer these three, I can do that too and omit the Pans. :)
