Need help making a competitive team

Hi guys I was thinking of making a team with Tapu Fini,Aegislash,Landorus-Therian,Gengar,Lycanroc,and Sylveon.Any moveset suggestions would be great thanks.

Smogon has a great variety of movesets for recommendation. I don't think it's a really good idea for us to hand pick each one for you as that is part of you making a team but we are more than happy to help once you get started. Check out this link and find the Pokemon that you want to use and check out their recommended movesets. Pick which ones you like and post them here so we can evaluate your choices.

What's good? Is this VGC or Singles? And bro you aren't usually allowed duplicate Items so most of those leftovers should be changed for something else. For the Fini I suggest maybe giving it choice specs or a scarf and teach it all attacking moves (not natures madness) or just slap an assualt vest on it. Maybe give the sylveon calm mind so it hits harder and just becomes an amazing tank also because it is obviously the cleric maybe give it an Iapapa berry so it can stay in longer. The lycanrock should probably have a focus sash if this is singles otherwise maybe consider the midnight form as this lycanrock is usually better on sandstorm teams in doubles (maybe you should try making one of those). Make the landerous timid and give it all special moves like earth power so it isn't phased by other landerous' intimidates and can knock them out with HP ice as it will be out speeding. If you want to make your landerous even faster put a choice scarf on it unless you went with that on your tapu fini in which case give it the choice specs for more damage. Maybe give the Aegislash a z-crystal and make it special with flash canon rather than the conditional gyro ball becuase there are a lot slower mons like mega abomasnow that wall it out.

I hope I helped. These are just my opinions and I would much rather you play with a team you like and want to use than just following what others say.

If you are making a competitive team, make sure you have no more than 2 weakness for a type. Your team is great but it seems to have no check for moves such as earthquake or a ghost type move.
I would recommend swapping lycanroc out for a normal-flying pokemon, such as Mega-Pidgeot. I would also suggest that gengar reverts to its non mega variant as the earthquake thing can wipe it out in one hit, negating its use for a lock-in perish song.
Also consider that half your team should be special attackers, the other physical. If you replace lycanroc with mega-pidgeot, you should probably make agislash a physical attacker by replacing shadow ball.
This is only my advice. You don't need to use it if you don't want to.
Anyway, hope I helped a little.

Problem is lycanroc is kinda garbage
