I would try to battle for competitive play but feel like I will fail at that.
These are the shinies I have
Dratini from 19th egg
Dragonair from 20th or 1st egg (following the first shiny Dratini)
Gliscor from 88th egg (longest hunt)
Honchcrow from 44 egg
Watchog (patrat) from accidentally running into bush
Magby on 18th egg
Shinx's on chain 18, 41, & 43
Electike's on chain 41, 42, & 44
The most shiny I've ever gotten in a day were 3 and it happened 3 times.
Right now I'm going to chain Magnemites and hopefully get 3 and I'll be done with that set.
