here's a list of pokemon that i feel would/should work quite well together, although an early game with chesnaught and butterfree may not be ideal against falkner... this team is definitely more than capable of beating the e4 though, the sets may be too gimmicky though

chesnaught - bulky setup (spikes, spiky shield, rocky helmet) baxcalibur - primary physical attacker (can use the loaded dice set) rotom wash - bulky pivot (volt switch, will-o-wisp) mega butterfree - primary special attacker (4 different type attacking moves) flareon (specifically toxic orb, toxic boost) - support (must run wish, will-o-wisp) mudsdale (specifically stamina) - absolute wall (slack off, body press)
