I am calling bullshit on this chart.
Maybe I got lucky, really frigging lucky during my play through back in 2000, but I never had trouble making a team

Mine was
>typhlosion
>porygon2
(traded with thunderbolt/icebeam at the same level as my party from blue)
>ampharos
>slowking
(found it early)
>hitmontop
(traded pokemon stadium reward versions to gold)
>umbreon

side duty
>donphan
>skarmory
>scizor
(got super lucky finding a magnemite with it)
>heracross
>miltank
>snorlax
>tyranitar


I had stadium 2 too so I had to have a larger roster

on side duty

>found a qwilfish after the first gym with the old rod
>can get zubat before the first gym after dark
>aipom can be gotten before the third gym
>found pineco in the ilex forest
>heracross outside of slow poke's well
>yanma outside of golden rod
>miltank before the forth gym
>corsola and stantler before the 4th gym


so what's everyone bitching about
the only ones that are total bullshit are
>Misdreavus
>sneasel
>houndoom
>murcrow
>magcargo
>donphan/ursaring
>Tyranitar

wtf were they thinking making three for lines exclusive to the last dungeon?
