I share MLGs feelings. For me the game ruined it and making even more pokémon. many were copies so that was also not the best ideas.
poochyena = houndour
plusle/minum = pikachu
linoone = furret
wurmple = weedle
beautifly = butterfree
shroomish = gloom
slaking = snorlax
skitty = eevee
Delcatty = any eeveelution (looks like the the normal-type eeveelution)
lairon = rhyhorn
aggron = rhydon
roselia = bigger bellosom
swalot = grimer/muk
grumpig = miltank (cow and pig I know, but look at the body)
seviper = arbok
corpish = krabby
spheal = fat seal
sealeo = fat dewgong
Not so many you may say, but the first I saw were all copies so that kinda ruined it for me.
I shall be a true GSC trainer (except maybe for meditite as I like that one, the only one I really like)
