Edit - Vormund, some lvl1 babies can have 11 or 12 hp, and 6 or 7 speed, etc, so you can easily pick off the "20-31" IV ones from the "0-19" bunch. For more accuracy you definitely need ~8-10 Rare Candies and metalkid's calculator, though.
------ question ------
I know this isn't enough info, but in a team based around Sp. Defensive Tyranitar + Defensive Gliscor (to abuse sand veil and the fact that they cover for each other quite nicely), what would be a good lead? Right now I'm torn between Taunt/Rocks/Psy/Explosion Azelf and Tyranitar itself with Rocks +3 attacks, but I want to find out what lead can support the duo the best. I'm also considering Roserade for Toxic Spikes support, but I prefer a lead that sets up SRock and/or Spikes (or both).
Thanks, I hope my question isn't too vague...
