Alright then let's see what we've got.
Hi to everyone who joined while I was away and on with the topic.
Elite 4 team for poison would be.
Out first and with such high speed it inflict early damage, immune to ground attacks
Dark typing to deal with those pesky psychic types, personal preference over Drapion.
Bulky water type for increased coverage.
Hits hard with leaf blade and leaf storm.
Levitating Pokemon with the ability to wreck foes with shadow ball.
To clean out any dark types. Good physical attacker.
Others considered were Arbok, Weezing, Muk, Rosearade, Nidoking/queen, Venusaur, Venomoth and Scolipede
