i need a bit of help with my team

[myheartencasedinice]

so for the longest time my pokemon team has consisted of Greninja, Charizard ( X cause i have pokemon X), Sylveon, Amphoros, Lucario, and Aurorous. I've decided recently that i'm going to take Aurorous off my team due to it's large weaknesses to common pokemon and it's not a strong attacker either which makes it not work that well on my team. Also my Greninja has ice beam ( so ice covered) and my amphoros has power gem( so rock is cover) which means my auroros really isn't needed when i have his type covered by pokemon with better defense. I've looked at the type charts and i have every type covered by more than one way and usually by more than one pokemon. the only types i don't have covered twice is fairy, and electric. Ground might also be and issue cause i have two good pokemon against it and two bad pokemon against it. also if someone send out a swampert or a rock water pokemon i might not have a counter. suggestions would be greatly appreciated! Also I've already beat the game so it's more for online battle purposes.

Ampharos and Charizard are only good in their Mega forms. However, I think that Charizard gets the nod ahead of Amphy because of the unpredictability of having 2 Mega Evolutions.

Well right now I have a sylveon that's a calm nature with cute charm ability and 3 perfect IVs in Speed,Sp. Def, and Sp. Atk plus he's a shiny so i want to keep him. His moveset right now is protect, wish, fairywind( when he get to the level that gets moonblast i'll get that) and psyshock. I plan on breeding my other pokemon for dfferent natures cause none of them are the right natures. I don't really have a pokemon with grass moves, which is an issue. I though Ampharos was the strongest electric type there is (outside of legendaries which i don't want to use any legendaries) i don't want raichu cause he's too weak and i don't know any good electric pokemon with a good move pool. I also still don't know a good pokemon to put on my team or rather good pokemon to use, i have a tyranitar but i don't think he's be good with my team.

In case you're wondering, Rotom is not a legendary; it can breed and multiple ones can be encountered in the wild (though it's rare).

i thought you could only get rotom through a special event or if you have black or white which i don't have. although that is a really good idea.
