lucario and zebstrika's weak to ground so you need some kind of flyer or levitater on the team, doesn't necessarily have to be crobat but crobat does resist fighting x4 so it covers lucario's and umbreon's fighting weakness well, same for cofagrigus. if you have flash fire arcanine instead of intimidate, he can cover lucario's fire weakness.
zebstrika is very useful because of volt switch. i use cofagrigus instead of chandelure just because i love cofagrigus a lot, but also if you switch into it with volt switch you can disable their ability when they hit you and that does sometimes come up. and then if you hit them after that your mon's ability gets replaced, so you could in theory replace a bad ability like archeops.
realistically one of the mons would be the starter, and that would be samurott. i just like how most of the mons have few weaknesses and several immunities.
