It's good, just make sure you play to each pokemon's strengths, eg physical fire move for Darmanitan is a MUST, as you get STAB and it has a beefy attack anyway. I personally would choose Chandelure over Beheeyem for a special sweeper, as it has higher sp. attack and higher speed, although the tpe difference may be not to your liking. Samurott is acceptable, but it's base stats are nothing phenomenal. Hydreigon is a brilliant choice, it's a generally sturdy pokemon. Lilligant is just not my sort of pokemon, but use it with Sunny Day is it has Chlorophyll, and its speed should do it well. Eelektross is good, as it has no weaknesses, but just watch its speed, as in online games, speed is often the difference between winning and losing, unless using slowing moving walls.
