Lucky you; I've only gotten one egg so far (there should be a blimp carrying a Rocket Admin somewhere near me though since I have the radar active) but all I've gotten so far was a Scraggy.
Normally I'd be ok with that, but I've already evolved the Scraggy I had after hatching one egg earlier and walking a billion miles to get the rest of the missing candy. Now that 12k egg was worthless. I'm hoping the one I'll get later today will have a pokemon I don't already have (Vullaby, Sandile, or Pawniard would all be great).
I've now gotten a different pokemon almost every time lol.
2x Larvitar (I've already got a pretty good Tyranitar, at worst this is just 2nd move Candy)
1x Vullaby (2 star, bordering three. Hoping I can get one again with better stats then evolve)
1x Pawniard (Same as above; nearly identical 2 star stats. Gonna wait for another egg to see if I should keep the Pawniard I have)
1 Scraggy (Just extra candy now. If I get another, I can can have him learn a second move, but I dont know if I'll use him in the Go League)
I've got one 12K egg going right now and I'm annoyed Giovanni himself didn't give one, but he does allow you to catch a Mewtwo, so I guess its a fair trade lol. The Mewtwo I got has awful stats and is weak as balls, though. At least I've got one with near perfect stats from an earlier Giovanni research encounter.
