I'm trying to be forward thinking about a team that can beat my friends and possibly people who actually play competitively. My friends will 100% use their in game team with little concern for natures and IVs and all that.

So far I have:

Calm Ivysaur = SpD wall
Impish Gligar w/ Immunity = Def wall
Adamant Electabuzz = physical sweeper?
Serious Ninjafrog = Don't really want to use because...everyone already does.

Of the one's i'm currently using for the story as backup: An Adamant Beldum and an Adamnt Speed boost Combusken as well as a shit nature Butterfree and a Lax Snorlax which I think it's the wrong nature boosting def and lowering spdef which is obviously better for him.

The Immunity Gligar and the Adamant Electabuzz are the only ones that were actually bred, the others were soft resets or luck.

Also, i don't know shit about the makeup of a real competitive team so advice on that would be amazing, even if it means getting other mon or dropping ones I already have.

TLDR: I don't wanna be bad, I could use some advice on competitive battling. I'm pretty Karenfag usually, trying to fill team roles with pokemon I specifically like if possible.

Pic related, My favorite Pokemon...probably.
